Guest guest Posted April 30, 2012 Report Share Posted April 30, 2012 Pete, I'm having some trouble understanding the new TLC7. On the reports page, why are ratios read reversed such as beta/theta? On the analyze page under Heads-Hot Temporals, what is the difference between T3 and T4 vs. T3%L and T4%R? And what does that mean? Under Reversal, it appears these numbers are ratios. So if L/R beta ratio is low, that means beta on the left is low compared to the right? and the same goes for R/L alpha? Is there a typo regarding O1/O2? Should it read O2/O1 regarding the R/L alpha? Thank you. Mike Quote Link to comment Share on other sites More sharing options...
Guest guest Posted May 1, 2012 Report Share Posted May 1, 2012 Thank you, Pete. Very helpful, but one more question, please. What does T/B ratio activation mean. How should we interpret it?
