Leather's Shedding: How Often

[Racso]

Ok, I have 5 different leathers in my tank, and each one is different on the shedding. The finger leather sheds about once a month, a different leather sheds almost weekly, and I'm worried about it because it is only open for a day or two a week, the rest of the week it is in "shed mode." A cabbage leather has shed a couple times, but months apart, my toadstool went into a shedding mode once, but I never saw it actually shed. Another one I've NEVER seen it shed or even act like it.

So, how often to leathers shed?

apparently there is no trend amoung them....

just as a note, I know that shedding is gennerally good, but like shrimp, can they over shed?

My Pink and my Green Toadstools shed about every 2 weeks, my Finger about every 4 and my Yellow Fiji has yet to shed.
