After tons of optimizations I was able to get it up to 10% of the data I have. I’ve intentionally introduced a bias towards winning builds. Very slight for now, but it’s slightly improved this. Once complete I’ll offer an API for inference on both weapon and builds embeddings.

holy shit this worked way better than it had any reason to. This is only on 4% of the data I have and it's already surprisingly good. What the fuck lmao. This is weapon similarity via kit choice as per @/stat.ink data
I’ve been trying to work on what I can best characterize as a gear autocomplete and it’s having me deal with datasets that are too big for my measly 128GB of RAM. 25 million rows x 200+ columns 😭

X Battle Top 500 player activity. Note that the increase after 6.0.0 is due to the changes in the way XP is calculated after series, which shows the Top 500 is significantly more volatile ever since they implemented those changes. This is a bad thing for a ranking system.

Ever wonder who the strongest players using a weapon are and how often they used it to get their xp? Want to compare peaks? Wonder no more! I've released a leaderboard for this. It's late so I can't fix a bug that says "Service Unavailable" but it works! splat.top/top_weapons

Here's a preview of the upcoming rework of splat.top! Ontop of everything you can see in SplatNet, I've added which region the player belonged to last season!

I made a video of the evolution of the Top 500 distribution vs X Power, each frame represents a different day. You can see how it evolves, it's kinda neat actually

Here is the final, true distribution of SendouQ Season 1. Lots of work went into this, I'm happy with it. But the neat thing is I can finally debunk the argument I see everywhere online, that skill is distributed normally. It is not, it is distributed log-normally.

More SendouQ data! Here we have the distribution of scores (and the tier borders) for Season 1 for all players who had a calculated score.

Hmm given @Splatoon3ink’s rotation and top 500 data, it should be possible to relate weapons with the best map/mode based off of changes in xpower. Since it doesn’t decay, any changes are guaranteed to be from play. Good thing I’ve already scraped all that data, now to analyze :P

Using a Cas9/guide-RNA-based gene drive system, researchers have produced mosquitoes that produce antimalaria antibodies. If released, models suggest the mosquitoes could reduce malaria incidence by roughly 90% within three months. In PNAS: ow.ly/TQLq50P9rGG
