if it was 3.03-3.77 as you suggest, a few things would need to have happened:

Nf6 would have needed to fail low
Possibly several other moves would have needed to fail low
Nf4 failed high

So what I am saying is that, for this analysis only, that a wider window would
reduce the chance of Nf6 to fail low, and hence why I think it was a
narrow/narrower window.
