It wasn't misinformation in my case when I replaced three membranes in a row after only 2 months each. And they were
wrecked beyond reckoning. Like, input TDS of 200, output TDS of 190. It really stung me since they tend to be about $100 a pop.
I'm trying to save others from that financial hit when I post about the short cyclings .. I honestly don't know what the difference between your setup and mine is, I'm happy it's working out for you but to be blunt, I don't understand how you're immune to it while I wasn't .. I'm jealous dude.
