Okay, my site is probably pretty relevant for what you're looking for.
180pedia.com/every-lsat-practice-test
The site is unpopulated with it's own explanations currently as I am working on a minor bug. Submissions are still welcome...
just avoid the following characters please ' " < > \
Details about the site can be found on the front page... will remain open and free.
If you click on a question page, scroll to the bottom and there will be links to explanations from 7Sage, LSATHacks, Manhattan Prep Forums, PowerScore Forums, and Velocity LSAT Prep when they are available. This is up to date for all questions up until about a week ago. I am in the process of trying to optimize a way for when new threads are created. Occasionally, there may be another thread explanation for a given Manhattan Prep and PowerScore for a specific question as they have repeats. I picked the explanation for those I found most satisfying and helpful. They will link to the respective page or thread for that source. I think the formatting of my site is probably a bit quicker and easier to use.
A few short cuts if you end up liking it...
For tests
180pedia.com/lsat-pt-#
where # equals the common PT reference (1-80, A, B, C, C2, F97, J07, etc.)
For questions
for LR: 180pedia.com/lsat-pt-#-section-X-lr-Q ( i.e.
https://180pedia.com/lsat-pt-68-section-3-LR-21/ )
for LG: 180pedia.com/lsat-pt-#-section-X-game-G ( i.e.
https://180pedia.com/lsat-pt-13-section-1-game-4/ )
for RC: 180pedia.com/lsat-pt-#-section-X-passage-P ( i.e.
https://180pedia.com/lsat-pt-68-section-1-passage-1/ )
where
# equals the common PT reference
X equals the section number (1-4)
Q equals the question number (1-26)
G equals the game number (1-4)
P equals the passage number (1-4)
For LG and RC, you just use the game or passage number. The explanations are based on game and passage.
If you have any suggestions or like it, LMK... I think it's pretty on point for what you are looking for. (well, it'll make it easier to cross reference explanations from different sources IMO) Sorry for the long post!
