Front Rail Keypin Alignment Reality Check

I think I'm obsessing again. Everybody knows that you bent front rail keypins slightly to evenly space keys. But when I do that I get increased key friction - which seems reasonable as the keypin is no longer parallel with the long (depth) axis of the keypin mortise. But I hadn't really noticed such a problem previously, nor have I ever heard anyone address this.

I'm doing this on a keyboard with nice new key bushings. When the pin is aligned with the mortise slot, there is near zero friction. But when you bent the pin to move the key over, friction picks up real quickly.

So what's going on here??????
