Especially good strategy for possible double parity.
Say, if you get OLL parity which you can see after the F2L, just do OLL and don't care the flipped edge.
then, check your corners. these are what you can get:
1. All corners solved.
for this, check whether your edges can do any edge permutation, regardless of the OLL parity, ie, U, H, Z perms.
if yes, do pure OLL parity to fix the bad edge.
if no, do pure double parity, den PLL
2. 2 corners solved. (either adjacently or oppositely)
check whether you can solve edges with EP. if yes, good luck. do pure DP.
if you can't solve edges with EP, use OP.
that way, DP, if it exist, can be fixed in one alg. In the long run after your recognition gets better, it should be faster than the traditional way of fixing OLL parity before OLL, and PLL parity before or after PLL.
