theres a difference in Overhoned and Alot of hone wear. you may be asking the wrong question.

overhoned : is when you create your bevel, make it keen then continue to hone which ends up making the edge wirey. i think one of the easiest way to tell this is if you touch the razor to your face to start shaving and you cut yourself... i look for an overhoned edge.

alot of hone wear: you mentioned above taking a blade fomr 3/4 to 1/4 and if it would still shave.. YES it will. you can still make that edge sharp and shave with it. understand that in this dramatic example you have changed the shape of the razor, honed past the hollow ground etc etc. however, the EDGE can still be made keen.

so Overhoning talks about the edge becoming wirey, past keeness. while alot of hone wear talks about change in shape/size of the actual blade as you asked about in your question.
