I'm with FRW, you can acyually get away with flying once in 4 years and being legal.
Pass PPL, just inside 2 years later take profiency test to re-validate, just inside 2 years later go flying. Sum total, maybe an 1 1/2 hours dual in (a shade under) 4 years - riduculous.
IMHO the 5 hours every 13 months was better; not perfect but better(and a darn sight simpler)
