What I actually said.

I think the biggest takeaway is that the new 50-200 absolutely destroys the 40-150 + 1.4x if you want to shoot at 200/210mm. (PL => 73 lp/mm, O => 52 lp/mm).

If you don't think a 40% difference in linear sharpness qualifies as destroying the competition

Well, if you adjust those numbers to the 16mp sensor that the 50-200 was tested on, then the difference will be smaller, probably closer to 10 lp/mm than 20 as shown above. And that is only a measurement at the longest end, so hardy a full picture. Adding in the natural sample variation and the picture is not as clear cut as it seems at first glance.

That's certainly true, but Lenstip also claims that there's only a small (5-7 lp/mm) difference in results between the E-PL1 and the E-M5ii.  I think we actually had a discussion about this a few months ago.  I'm still not sure I believe that claim from them though.  Sample variation is certainly a factor but quite a few sources show poor results from the 40-150 + 1.4x combo, including my own experience, so I'm inclined to believe that Lenstip's 40-150 results are reasonable.

qualifies as destroying the competition (and that's ignoring the garbage bokeh the 40-150 produces, especially with the TC) then I don't know what does.

Actually, I would say the tendency to produce unpleasant bokeh on Oly is a bit more definite disadvantage here.

Yeah, this is by far my biggest problem with the lens.
