I am also doing it on 3.23.33 with MyISAM recover options off, is that what is happening? like I
said...if I delete record one, and add a fourth record, It DOES NOT add it as 1. But as 5.
however, if I delete 4, then add a fourth again, it sets it as 4. I'm not sure if that has
anything to do with my MyISAM settings or not..but there you go.

What version of MySQL and table type are you getting that on? I just tried
it with a MyISAM table in 3.23.33 (insert, immediate delete, immediate
insert), and the pk incremented as expected. No re-use of values.
