A wayge is dependent on the activity it is measuring.
This is the formula for working out wayges
at / ax = lim (ax -> 0) (t(x+ax) - t(x-ax)) / (2ax)
where a= activity
" " t=time
and x=a random letter to add complexity.
If you are playing super metroid and it takes you longer than a day to complete, that's wayges
