What is the best way to calculate average sales cycle length per (Rep, Class, ect)?

Ok - just making sure I understand correctly - you want to know how long by sales rep what the average time to close on an Estimate is?

AVG {daysopen}?

I actually used opportunities, I took the date created. the date status was changed to closed won, converted it to age in days, then did a numeric formula to calculate the difference, used average as a summary type. We touch leads way before estimate, so while that makes sense for companies only giving out estimates, our sales cycles are much longer.

So you figured out your search?

yes thanks
