I am thinking I should keep a record of how many papers are accepted versus how many rejected.

So, in answers from last month:

6 poems submitted, 2 accepted, 4 rejected

5 papers (as opposed to presentations) submitted, 2 accepted, 2 rejected, 1 pending

I have tried to be very careful in placing my work where it is most likely to get accepted. Even with that, my acceptance rate is a 2:3 ratio.
