Feet-a-diddle VS. Para diddle

So what the heck is the difference between a feet-a-diddle and a para diddle, well seeming how RLRR and LRLL are still directions it is technically still a para diddle. Why do these help with your feet though? I understand independence, the more things you can do with your feet the more your beets you can play naturally. One thing that I found, is I get a different sound when I do a RLRR pattern instead of going RLRL with my feet, doing a double pattern with your lead foot may be more consistent then ending on your weaker foot. So in an instrument such as double bass and drums, where anything goes if it is sound that can be recorded on time, why the heck not. Also if you do double taps, you don't always have to do a clean para diddle, but just end a double tap, so RL RR with the RR being a double tap. The double tap can be done with a heel toe method or just a double tap. Don't know what the exact name for it is but I call it when a punk drummer is trying to sound fast on single bass. Lotta double tapping going on. So try it out, don't just continue to think that playing everything RLRLRL is going to get you through the world. I learned the hard way, I bought a drum book that had some double bass in it, I spent about 1 minute looking through it and it reminded me to try stuff with different feet patterns. The only way you will ever find out what it does, is by actually doing it. So don't be lazy, grab the metronome and practice your diddles, but also different alternating sticking and footing patterns for double bass.
