. This is comparing to to Core i7 920. Compare it to Core i7 2600K.
Core i7 2600K = Core i7 3770K = Core i7 4770K when you bring on average overclocks.
That's some horrible math. Every time the base to calculate the % change increases and therefore you can't just add 15 + 5 +5 at the end.. The number should be larger than 25%, at least mathematically. I'm not sure this is what really happened with the CPU performance but I believe your calculations are wrong.
Also saying "Core i7 2600K = Core i7 3770K = Core i7 4770K when you bring on average overclocks." is a pretty bold statement. First of all, what data do you have on "average overclocks"? just casually browsing the forums is not really reliable or representative of the average.
Finally, if that was true, nobody would have a 3770k or 4770k since they are harder to cool at higher OC than the 2600k,and the latter can reach better OC for this reason.
