For example, it could be possible that okechedy is very rare, because it is preferably written opchedy

I am not saying that I think that that is the case. It is just a valid possibility.

If we assume that okechedy = opchedy, and we assume that the preference is to write it opchedy, wouldn't that then require a reason (e.g. subject matter) for the opchedy/okechedy word type to be so predominantly on the top row?  And we would likely have to do the same for the other /pch/ and /kech/ words in the list too.
