I would like to look at the v2 when it comes to harder LN maps with HR. As a pretty decent LN player I tried some things out and I was astonished with the results. On the screenshot below you can see that I had a pretty good acc and nice score. However I FAILED IN THE MIDDLE because LN releases on hr are so incredibly tight that you get a miss on what would have been 200 (or even 300) on v1 nomod. This is so hilarious when you hokd a good acc then the denser sections come and you fail so easily because of high HP on HR. All but 1-2 of the misses were because of stupid release windows. Despite my efforts to release as precisely as I can, I still died. The release windows on HR should be more lenient, especially when it comes to window for miss. I practically have not received other release judgments than MAX, 300, 200 or miss.HR was being added twice to the hit windows. I've pushed a fix (only on CE for now) that rectifies this and modifies all other timing windows sliiiiiightly so they align with MAXs a bit better by interpolating from OD0-OD5 and OD5-OD10 instead of linear scaling from OD0-10.
My suggestion: either increase the miss window for releases (with making the 100/50 windows wider as well), or change all of the misses to 50s which will prevent failing the map so easily.
Please test again.
