 The double-check, which takes just as long as a first-time test, is usually done about 2 years after the first-time test.
I'm finding that most of the double checks I'm doing are 7-9 years after the original.

LL gives an absolute and provable answer. PRP is gives a probable answer. If a PRP turns up a new MP, then LL will have to be run to prove it.
