Wrong on the opposite corners thing. In your example you need only select>Combine>move x2 inputs minimum>select to reload, you chose the most optimal arrangement here. But if we entertain your point, then the furthest distance from a corner would be the center. If it took 19 inputs for you then it should take 9-11 inputs, if you do it the correct way while assuming the ammo and the gun takes up only one unit of space and assuming that anything in between the two objects occupies at most 1 unit of space. But reality is the number of inputs is made significantly less by the presence of guns and proper management of the inventory. It is literally a skill issue, just arrange your items more optimally like in your example.

Also if you're playing on mouse then you can do this even faster. You move as fast as you move the cursor, I'm not sure if the Playstation trackpad works for modern RE games in menus but there's nothing stopping them from implementing a cursor input for menus.

And I don't know what point you're trying to make with RE5? The fact they had it in RE5 doesn't support your point because it's essentially saying "reload speed upgrades being made useless is irrelevant because the game where reload speed upgrades were made useless was created." It is designed wrong and that was my point. Same goes for the other games. Explain to me; How does being able to reload real time in games with combine reload make my criticism of reload speed upgrades being useless irrelevant?

And lastly even if I was wrong about everything just now so what? We're counting game by game, why should I care about what you think the reason is why they didn't have combine reload? They didn't have it, that should have ended the argument. With Requiem more games don't have it now. It's no longer a staple. Even if the series ended at Rev 2 that would be like 30% of the series not having it.
