Eh, it was what the D&E guide originally said to do about STAB, but I've since changed to just 1.1x, rounded up, in the battles I've taken since then, with slight modifications on a case-by-case basis (e.g. multi-hit moves).
In other recent changes, I can tell you that your battle is currently counting stat stages as a 1% boost each, rather than a 1.5% boost as is usual these days. I have since changed this.
