Yea TE & NPA are indeed

the same formula as belgareth mentioned. Yet when i think about putting PI on, I also think of NPA... as the

consentration of `mones in it is about the same They are indeed different, but I like to each time try one of the

two as they have similar results... I mean... only slightly different results hehe.
Anyhow thanks for the advice.

Interesting concept indeed
