Things like overhealing cannot really be accounted for on my side, since I have to work with the information that is in the combat log. This also means that I won't be able to analyse the decline of CPB/TachBeam since these abilities don't show up in the log.
The first preview chart shows average magnitudes over time (something like a ship equipped with one normalised copy of EPtS/ES/TSS/...). The situation will improve a bit towards non-BFI healing when we look closer at absolute healing numbers and start adding some things instead of averaging them.
I'll also be able to look at some data from premade matches prior to BFI/TT for comparison, although I'm afraid that the earliest data points I have (Dec 2010) won't be particularly meaningful since these are the super quick SW wins in the KT league. But I am confident that there will be some useful mid-2011 logs.
