I did check and the rate is 49.6. That is an improvement over a few years ago. I do understand the thinking, but there is a little problem with that. The first problem is that what if you don't score another TD. As happened to the Titans. That point is gone. Also, if you do score another TD, and kick it both times, the chance that both will be good is a little above 85 (based upon a 92.5% success rate through week 14). If you try two points twice, the chance of missing both is 25.4 and I think that means that you should hit at least one 74.6 % of the time, which is less than 85. So, in my opinion, you should still kick it.
