Recoil is subjective and rifle fit does make a difference. I do apreciate the time spent putting the table together as it gives a comparative idea about difference in recoil, especialy for the big ones. I also no this, I put 26 rounds threw the .375, 10 rounds threw the 416 and 15 rounds threw the .458 Lott yesterday and the first thing I did when I got out of bed this morning was swallow a hand full of tylenol.
I agree, recoil is something one has to learn how to deal with. I have found that a synthetic stock has a lot less recoil felt than the pretty wood stock. If you don't believe me I'll put the wood stock back on my model 70 - 30/06 and it hurts like heck after 3 or 4 shots. With the synthetic stock you can shoot all day with it using 150 or 180 gr loads. The same with my 375 H&H. I'm not convinced that those charts & statistics on the felt recoil is correct!!
I've heard (and experienced) the same (in my case, though, there's not enough information to go on...one rifle, two stocks, one wood and the other synthetic, but also of slightly different form).
I think the reason is time in that a synthetic stock flexes more thereby reducing the amplitude (recoil energy can be thought of as area under a curve...the area may be the same but with the time function longer, the peak amplitude is diminished...this is the entire principle behind crumple zones (and air bags) in automobiles).
