>>16709744The pentaperfect 14 are seven 31/31/31/xx/31/31 and seven 31/xx/31/31/31/31 of each group as opposed to seven 31/31/31/31/31/31.
They difference (lack thereof, rather) between pent14 represented by Parent A.
Parent A is either your pent14 or hex7. They yield the same rate of successful offspring.
Parent B is the female Pokemon which can have any spread. Parent A being either pent14 or hex7 will have same results.
The only difference between pent14 and hex7 are two:
1) Pent14 is far easier to breed.
2) Hex7 is more useful in the rare case that you need a 6IV offspring.
