Sure. At one point I was tracking total time for Jenson and Lewis and it was remarkably close. They both had races finishing a good ways in front of the other. But if you'd like to go the anecdotal route Australia 2012 is a good example of a head to head dry fight between the two. Lewis had the edge in qualy for sure but there just wasn't much between them during the races. Comparing which of them secured the quicker race lap results in a 27-27 tie (barring a few races where one or the other was unable to set a time).
Your turn. Tell me how you know that "Kobayashi was very quick in qualifying"? Compared to who? His 2010 season he was out-qualified 11-8 by a combination of Pedro de la Rosa and Nick Heidfeld. Good solid F1 drivers both but neither a Q ace.
"seeing off Jenson in a lesser car" is another straw man. Was it a lesser car on the tyres it was on at that moment? I also remember him throwing away a chance at a win in that race against Alonso. Forgivable for a young driver but not exactly a sign of greatness either.
The point is that I'm just not convinced that Perez is a potential top-tier F1 driver. He might be, and since he seems like a nice kid I'm certainly not rooting against him. But the evidence for him being one so far is a couple of races where he had a tyre advantage because he didn't make Q3.
The evidence against him is that he wasn't that impressive in Q in GP2. All of his peers secured more poles (Hulkenberg 3, Grosjean 3, Maldanado 2, Senna 3, Petrov 2) at that level over a 2 year span. He was younger than all of those at the time so we have to cut him some slack, and maybe he's Jenson-esque in that he doesn't care so much about qualifying and keeps his focus on race setup, which would be nearly remarkable in a young driver in GP2.
Edit: bold for clarity
Ok race pace calculations have to consider the fact that with pirellis the guy in front almost never has any need to rag the tyres. Therefore as Lewis was mostly in front in an identical car we must expect the overall times to be close and look evenly matched, we should therefore look for who was mostly infront and how many times one overtook the other or if they were equal in this respect. If one was mostly in front then we must understand that the other generally didnt have the pace to overtake. Then we look to grid position and therefore opportunity to overtake, I think we should conclude that Lewis overall had much better race pace. This is assuming your data has removed all the spikes caused by things not relevant to this metric.
The anecdote is fair. There are other examples that tell the other story but we are not saying who was faster once in a while etc but who was generally faster
Kobayashi was consistent in the Sauber in qualifying, no it doesnt look good loosing as a rookie to PDR but Heidfield and Trulli are different story. He was good enough to consistently get the Sauber in Q2/1 , even got podium quali in the dry if IIRC. This is not a guy who is bad at quali but ok I give you that one, he doesnt stamp perez with legendary status
seeing off Jenson = done it already, likely to be unfazed on track in same car, tyre etc irrelevant, more the kid in lower team vs star in fast car geddit? same as for Alonso, sure he spun, some say Ferrari caused this, all Im saying is the kid is not fazed by guys higher regarded by him.
Whatever happened in lower formula doesn't dictate what will happen when he takes to track in the Fastest car.
You have to admit that apart from the last races last year he has somehow stood out head and sholdiers above all the other rookies, bar maybe Hulk. He got the McLaren seat didnt he?
Lets see what happens in the races but I reckon we are going to see him step up to the plate and surprise many many
