During the week of August 22nd 2018, I turned off mouse acceleration for the first time ever. I adjusted my sensitivity to something I felt comfortable with, and started playing like that instead. The very next day after this switch, I started to gain ranks and improve at a substantial rate. I was around 67k rank before with a top play of 142 pp or something similar, and in a week I had 200 pp plays at around 35k rank. After that, I climbed at a slower but still fast rate relative to other players, and reached 20k sometime in the next month. I kept climbing to where I am today (end of 2019), with very little time periods where I was stuck in a dry spell.

During the start of November 2018, I discovered that I could no longer submit scores on beatmaps ranked after October 28th on my fallback client, which was the only one I could use on Mac that I knew of thus far. yeahbennou linked me a Github download of a Stable osu! client ported to Mac, which I now use to this day. It still has all of the problems that I listed above, but is much better than the Fallback version listed on the website.

Near the end of December, I got a Huion H420 tablet. I tried it for about 2 weeks, discovered I sucked at it, and moved back to mouse. Maybe I should have tried it out for longer, but I think I made the right choice.

In April 2019, I finally upgraded from my 7 year old mac to an actual pc that I picked the parts for and built. Also got equipped with the obligatory 144 hz monitor. I also switched from my old rubber dome switch membrane keyboard to a mechanical keyboard with cherry mx browns. My acc now sucks ass still after 2 months of playing with it, but people tell me it's just a learning curve I have to come across, so I'll continue on with it. My speed, stamina, and aim have improved tremendously with my current setup, though I still have the crippling weakness of not being able to read ar 10 and not being able to start triples or bursts with my dominant finger (???????).

2020 Summer: got a Ducky One 2 keyboard with cherry mx blacks, always preferred heavy switches so here goes. Maybe acc will improve

2021 Summer: after 6 months of not playing much at all (after mrc 2020) I started playing again and am setting some pretty good scores. Not going to focus on tournaments that much (already have 2 badges and some good solo performances) until I get good enough again to match the other 4 digit tournament gods still around.
After playing with only hr for a couple of weeks, my acc has improved more than it ever has before which let me set a ton more plays that I can actually be proud of, and my global acc has finally raised to above 98% again.

2023 winter:
Grinding speed/stamina and also doing some ar11 plays. when will i finally be good at the game ?
