Default Re: 720 rule vs LCD

Oh - BTW - one other thing that bothers me about the way the 720 is being presented on this forum is that in almost all cases when someone asks about the 720 rule the following is quoted.

minutes = 720xmls/ASF

This really evaluates to a constant based on what constants one picks for mils and ASF. This only answers the question of HOW LONG.

What we really need to do be poining out to newbees is the other half of the equation which is they need to multiply the ASF x the area of their part and set their current for that. Only then do they have all the information they need to produce results.
