That would be the optimal situation but the truth is that RS tyres are so much faster than RH that even if you pit every other lap you'll still win. PD really screwed up when they started playing with the tyre degradation values. There's still no strategy if you have free choice of tyres, RS will always prevail if the race is a long one.
I think the Ferrari times matching at Spa with comfort soft is more due to the fact of unrealistic downforce. It's difficult to find a good combination but I'm with most people here, RS tyres are boring to run. With GT500s, RHs are really fun to drive.
I'm really hoping PD would adjust the rates at which tyres wear. Softs could stay as they are (or go back to how long they lasted before the update), but hards need to last a lot longer to compete against the speed of softs.
Tyres/PP is like the difficulty setting in this game. The lower you go on the tyres and higher on the power the more fun it becomes.
If you watch the video I posted on youtube (not just the video player thats showing in the post) and look at the description at the bottom of video there is details of most of his tune that I used along with my own lsd and suspension settings since they weren't provided. The downforce listed is 90 front rear 120 and that's less downforce than the default for the f2007.
Although you could have been referring to unrealistic downforce of that particular car in gt5.
Another thing to think about here is the Mercedes driving challenge that happened last year. Tires were restricted to comfort soft I've been researching the tires for that car and this is what I found below in a review.
"In front, the SLS AMG wheels are 9.5 inches wide, 19 inches in diameter, and are shod wîth 265 / 35 R 19 tires. The rear wheels measure 11.0 x 20 inches, wîth 295 / 30 R 20 tires that are nearly a foot wide. The SLS AMG tires use an exclusive rubber compound wîth grip on dry surfaces
that's comparable to today's road racing tires, but wîth none of their disadvantages in the wet and cold"
and I found this
"Continental Supplies Tyres for Mercedes-Benz SLS AMG "

Further approval for new ContiSportContact 5 P
Tyres deliver best combination of sportiness and safe handling
Worldwide cooperation between Mercedes-AMG Driving Academy and Continental
Car Tires
Hanover, 10 June 2010. The new ContiSportContact 5 P, part of the portfolio of high*-tech tyres for sports cars and super sports cars since spring, has now also been approved by Mercedes-AMG.
So from all of that I take it that comfort softs are comparable to these contisportcontact 5p which are comparable to todays road racing tires.
