We'd like to determine how long it actually takes a deal to close from the time we first receive a redline. Frequently, a workflow is created and a document goes out but no active negotiating takes place for a long time which makes the average time to close look much longer than it really is. Is there a way to determine time to close from receipt of first redline vs from workflow creation? We have turn tracking enabled, although from what I can tell it's not used reliably.
