Yes, fuck off with you study chamber shit. But I'm beginning to think ABCD = ABCd; HOWEVER, not that ABCd = ABCD. These are saying different things. Put it this way; all ESTJs are LSEs, but not all LSEs are ESTJs.
I don't agree completely though; I haven't yet been fully convinced.
For example INFP = EII and INFJ = IEI doesn't quite work, because Expat's showed so. Nor do I think ENTJ = LIE.
ESTJ = LSE
ISTP = SLI*
ISTJ = LSI*
I'm particularly confident in these two after having read about them. Those are the ones I'm almost certain of.
