Top Law Schools

I looked on the cambridge LSAT conversion charts and looked at the tests beginning in 2006 and noticed a pattern that the December LSAT's have overall had a more generous curve than June/Sept.....what are some factors or possible reasons behind that?

Is it because since the scores are curved/equated some top scorers are satisfied with their June/Sept exam and do not take it in December...or are the December LSAT's slightly more difficult so therefore a more generous curve?

I would doubt LSAC intentionally decides to make the Dec LSAT harder year in and year out these past few years but I could be wrong

Has anyone else found that the looser the curve, the higher your scaled score ends up? I've recently gotten into the middle to high 170s, and the tests with the looser curves, although they feel slightly more difficult as I take them, result in a higher score. Basically, since my raw scores are fairly stable regardless of test difficulty, I've found that I prefer the looser curved tests.
