alumina hydrate in kilns

I saw the URGENT WARNING about using Alumina H. for kiln wash. I've been
using a wash of:
3 parts (by volume) Alumina Hydrate
2 parts EPK
I've fired to ^10 about 60 times and my elements seem fine. I thought the
high temp would wear 'em out fast but this seems like an O.K. track record
to me. How many firings should I expect out of a set of elements at this temp?
