If you look at the score sheet below, the answer to “Why VolleyWrite?” is self-evident. Aside from the readability and penmanship, notice that the substitutions overflowed (not the scorer’s fault), incorrect substitution information was entered on the right (since when can #1 sub in for #1?) and there are no tic marks to indicate whether the correct player served. VolleyWrite formats the score sheet to always be readable and would not have recorded the substitution incorrectly. In fact, it would have prevented an illegal substitution.
