How does bottoming out create typos? Are you not getting your finger back off the key quick enough so it is duplicating characters?
Isn't hitting the wrong key, hitting a key not hard enough or accidentally giving a key too much pressure. Aside from a home row rest or feeling for nubs, why would someone purposefully put their hands on a key they didn't want to press and risk accidental presses.
I eliminate most typos the first week of changing to something that is different, but it can easily take up to a month of regular everyday use to adjust to a new board.
I think either have someone watch you type, to figure out what you're doing, or record your hands and the output to help isolate what the issue is.
Typos from not releasing a key fast enough, or accidentally pressing a key or resting one's hands on the keys, should be obvious causes, because those typos are going to look like aaaa or seeing the key you know your finger was on or hel instead of hell.
Are f & j in the same locations relative to your monitor, chair, et cetera as your previous keyboard? Keyboard orientation changes in addition to the change in keyboard size, key layout, et cetera, can all create a new layout for your muscles/brain to learn and increase typos.
I don't think we really have enough information to really understand the causes of the typos in this case.
