38 Spcl.(+P) -vs- 357 Mag, that's what you were comparing & said wouldn't matter. It does.
Your statement, "the tiny bit of extra velocity is not gonna matter", was incorrect & I tried to show you. It's not a tiny bit.
If it didn't we'd all be using a 22LR for SD.
Of course it does.
No one is criticizing what you use. Everybody can, & does, use what they want.

How does it matter? If you shoot a person with a 38+P do you think the 357 is gonna kill the person better?
You compared two different loads, which does make a difference. If you want to show some marginal difference then you need to compare data using the same powder same length barrel
Numbers by themselves mean nothing. If you want to compare then at least you FBI protocol gel test, shoot a milk jug or wet newspaper.
Besides reloads are not wise to use for SD, so the OP is limited to factory ammo. Compare all those.
A hole is a hole, watch the video by Federal that proves it, hitting a critical area is all that matters.
But there you have a ballistic debate.
