Lotta difference 62% / 50%. That many cycles to 50% would be good. 62/38 hmmm...
22-hours with twin Cree Reading Lights over my bed for reading. 12.77 volts showing on the 31 Lifeline. Next test is 8-hours of BiPap + 8 hours of Fantastic Endless Breeze, plus 5-hours of reading lights. This makes for a great hotel and car-overnighter at a gas station setup. In a car not for my rig.
Anyway, good-on-you landy...
That's a year and almost two months worth of everday of the year cycling down to 62% state of charge. Far and away better than the average RVers norm.
