I can't change the current columns as someone could rely on those, but i could add additional columns like the 2 decays, average current RV, average RV at T=0, lowest RV at T=0 for 4 cycles. I was also thinking of adding same type of columns but for a longer history like 3Y or maybe 5Y.
I will have to check how to deal with the number of columns as it's getting crowded.
You are perfectly right, and looking at the code it should be the case that BD<=CD but obviously it's not what we observe on the decay on some cases. I will have to debug the code to understand what's going on. Thanks for the feedback, it's a good catch.
