7D vs 70D vs 6D etc - Compare Bodies - SHUTTER LAG / FPS , etc

The 7D supposedly has 59ms shutter lag. I do not notice a change in going from my 7D to my 6D.

Pre-focused shutter lag on the 60D and 6D are identical at 0.059 seconds. I own both. I shoot both. They are NOT 0.290 vs 0.059. Canon makes one body that is faster out of the gate. I am not sure if it is the1Dx or 1DsN. Snapsort - crapsort. That is one of the few sites I can think of that is more worthless than Canon Rumors. Of course, if you found that information on the internet, it must be true.

I'm curious....
How could the 6d and 70d have the same exact shutter lag. They don't share many parts, do they?

6D and 60D. A Porshe 911 Carerra and a VW Minivan can both go 60mph. Why can't two different cameras have the same shutter lag? A cheetah and turtle can both walk at 1mph.

It all makes sense. I had no idea that site was garbage.
Revised original post.
Cheers guys.
