This is to MKSGR:
I don't know how many race cars you have driven on the Nordscheife, but I assume you have since you have so strong opinons. And I also assume (hope )that you are very familiar to data logging and lap timing analysis of the Ring.
Well, let's do some maths. Sport Auto lap is approx 20,6 km. HvS time is 7,38, Suzuki with the same car 7,29 (remember the rims on the 7,26,7 time where not the same as HvS had, so let's be fair and compare the 7,29 time with the 7,38 time).
Let's also assume that HvS acutally did drive 20,6 km (perhaps it says how long he drove in the Supertest?). Mr Suzuki did definitly drive a shorter lap than HvS (just look at the videos), let's say 100 meter (which is quite little). Which means that Mr Suzuki drove 20,5 km. Quite reasonable assumption.
That means that HvS average speed was 161,92 km/h and Mr Suzuki's 164,37. Do I sincerely believe that Mr Suzuki can be, on average, 2,45 km/h faster than HvS? Yes! Just look how he drives! All my experince of studying data logs of the Nordscheife says that that sounds quite reasonable.
