Patrick Middleton‏: Formula 1 ought to be big enough and cheap to support a World Championship and several other series, including one in Asia, and one a Southern Hemisphere series taking place in the European winter...A race every weekend, 52 weeks a year, even a race on New Years Day, 16 events per series at most. Anybody can enter any series or any race; no points if you don't attempt to contest all events in a series...

James Macdonald: I think the best thing would be 16-18 races, protecting a 'core' of annual classic races and alternating the others. Eg: Annual: BEL, ITA, MON, GER, GBR, JPN Years 1, 3, 5 etc: CHI, RUS, ABD... Years 2, 4, 6 etc: BAH, MEX, AZE... Fewer races mean each one means more.

Racing every single week of the year? Patrick's a tough taskmaster. When are we going to get our holidays?

Red Bull dominated both practice sessions yesterday, with Max Verstappen setting a new track record in FP2 - what can he pull out of the bag in qualifying?

It is drying up in Germany so there may be still use of the other tyres available today. We have the white mediums, yellow softs and purple ultrasofts available. As well as, obviously, the wets and intermediate tyres.

Can Romain Grosjean and Kevin Magnussen maintain their decent qualifying form? In France, Austria and Great Britain both Haas drivers got themselves into Q3.

In Austria Grosjean converted that into a fourth-place finish, his only points of the season, while Magnussen has come sixth, fifth and ninth in the past three races.

Steve Howes‏: Cars are too wide for most street tracks. Monaco first to go.

David M: re. Earlier tweets, Monaco reversed is a good idea. HK would provide a stunning backdrop but Macau is much too narrow for F1. Streets circuits usually poor for f1, though.

Will we be back in Germany next season? These fans certainly hope so.

It was only two years ago when Daniel Ricciardo unleashed his inner student and bolted down champagne from his shoe - the same shoe he had worn throughout a hot, sweaty race at Hockenheim - and 'The Shoey' was born.

No-one is safe from the celebration it seems, with Sir Patrick Stewart, Mark Webber, Lance Stroll and Gerard Butler, among those to have sampled the champagne from Ricciardo's race boots.

The Australian starts at the back tomorrow but showed his pace by being the fastest in the opening practice session so who knows, maybe another Shoey is on the cards this weekend?

There was no race in Germany last year, but 2016 has happy memories for Lewis Hamilton as he got the jump on polesitter Nico Rosberg at the start and then led every single lap on his way to the victory.

The top 10 were...

1. Lewis Hamilton (Mercedes)
2. Daniel Ricciardo (Red Bull)
3. Max Verstappen (Red Bull)
4. Nico Rosberg (Mercedes)
5. Sebastian Vettel (Ferrari)
6. Kimi Raikkonen (Ferrari)
7. Nico Hulkenberg (Force India)
8. Jenson Button (McLaren)
9. Valtteri Bottas (Williams)
10. Sergio Perez (Force India)

Tony Scudder: If you had three Americas races, four or five Pacific races, and then rest Europe, you could have championships for all three (same points) and still have overall World Champion too.

PhilSlocombe‏: I'd like to see another race in the Far East; either a street circuit in Hong Kong or using the GP track in McCaou, or even using both linked by the bridges.

jim Doherty: I'd switch things up, all circuits would be reversed. Could you imagine racing Monaco backwards!

This is how it stands in the drivers' championship after 10 of 21 races. Vettel's late move on Valtteri Bottas to take the lead of the British Grand Prix has given the German an eight-point lead over reigning champion Lewis Hamilton.

Williams have been having the worst season in their history so far this season, but they have taken to Germany a new front wing which they hope will solve the aerodynamic issues that have blighted the car.

In short, it tweaks the airflow with the intention of preventing the diffuser stall - or loss of downforce - that has been happening when the front wheels turn. Both drivers tried it, and Sergey Sirotkin was positive. “We never said this is something which gives us a lap time on its own, but we do see some good improvements,” the Russian said.

"It definitely gave us a more stable base, and a more stable airflow. That is what we can already see, even having not passed through the process of adaptation yet.

"From now on it is more about turning this more stable base into the performance which, obviously not having this base [before], we could not do in the past. It it is a step in a right direction, but obviously there is a lot more to come on top of it.”

David M: Axe the big money Bernie races - Middle East and Russia. And also Singapore and China even though they're my closest ones. Keep Europe, Brazil, Australia, COTA.

Benn, y'all: 17 rounds, from South Africa, Brazil, Mexico, USA, Canada, Monaco, San Marino, Spain, France, Britain, Germany, Hungary, Belgium, Italy, Singapore and Japan, to Australia.

Matthew Thomas: Dream F1 season = 15 races all at Spa Francorchamps with the British Grand Prix in the summer time, one GP at Monza for and round off in Brazil.

These were the times from a very reduced third session. No-one managed more than nine laps out there in the wet conditions.

Sauber’s Charles Leclerc was fastest in a soaking wet final practice session at the German Grand Prix.

The results were meaningless as a result of heavy rain but, after 40 minutes of no action at all, every driver did try out the conditions in the final 10 minutes.

The Monegasque, tipped for a promotion to Ferrari next season, was 0.423secs quicker than team-mate Marcus Ericsson, Williams’ Sergey Sirotkin and Ferrari's Sebastian Vettel and Toro Rosso's Pierre Gasly. Only nine drivers set a time.

Lewis Hamilton was not among them, but the world champion did do a couple of laps amid intense speculation that he might have some form of leg injury, which Mercedes denied.

Qualifying takes place in two hours, at 14:00 BST, and it seems likely that it will at least start in wet conditions.

If qualifying is wet, Red Bull are likely to become major contenders for pole position, which would be expected to be a fight only between Mercedes and Ferrari if it was dry.

A few wobbles late on, Lewis Hamilton nearly spins, Lance Stroll likewise. Luckily no-one seems to have done any damage and the question remains of how much can the track dry off in two hours before qualifying at 14:00 BST?

1. Charles Leclerc (Sauber, 1:34.577)
2. Marcus Ericsson (Sauber, 1:35:000)
3. Sergey Sirotkin (Williams, 1:35.334)
4. Sebastian Vettel (Ferrari, 1:35.573)
5. Pierre Gasly (Toro Rosso, 1:35.659)
6. Brendon Hartley (Toro Rosso, 1:36.151)
7. Nico Hulkenberg (Renault, 1:36.873)
8. Kimi Raikkonen (Ferrari, 1:37.755)
9. Lance Stroll (Williams, 1:38.393)

No other drivers set a lap. Yes, the session was ruined by rain but a Sauber one-two is in the history books for ever.

Odds on a Leclerc, Ericsson, Sirotkin one, two, three on Sunday? You would be very, very wealthy if you put some money on that and it comes in. And Sunday will be a crazy, crazy race if it does.

All this talk of Lewis Hamilton being injured, which Mercedes have dismissed, and the world champion has just got out on the track with a minute to go in the session to have a look at things.
