I'm back. See the picture for the numbers. Just look at the big table on top for the quickest results; or the one on the bottom for individual ranks..
If you want a quick summary, most categories of vtubers are either stagnated or dropping in views, when comparing april to may, which is to be expected since the quarantines over covid are ending, so people have less time to spend on watching streamers now. You can however see a slight growth of some jp groups mainly due to Golden Week happening, which got them a lot of collabs, tournaments or special streams such as outfits or 3Ds - you can expect those jps to fall a bit the next month
I made a quick test in removing many of the most special streams (10 costumes and 3 3Ds from holo; 5 3Ds from niji), but saw that their growth doesn’t fall that hard, as those streams are usually diluted by several other videos + all the other members who had a normal month. So for example, HoloEN goes from +21,1% to +7,5%; HoloJP from -1,5% to -4,5%; Nijifem from -7,4% to -9,8%, to give us an idea how much did those impact the numbers we see on the picture by the left.
The category ‘others’ had the biggest rise this month, but I wouldn't trust it much, since last month when I did the same analysis they had the biggest fall - guess they are really volatile to the situation. Twitch vtubers are also doing better growth than youtube ones [especially Nyanners and Ironmouse, they’re jumping up 10+ ranks each month], in a rough general, although they are still much smaller in their view/time rates.
I’ll post down below the vtubers ranks history I'd collected updated with this month as well.
I’m using the metric (vod) views/time because it seems to be the best metric we can use for comparisons. There’s no way to calculate direct hours watched without having access to data analytics from inside each channel owner or bullshit it; simply counting total views doesn’t take into account how much did they stream to get there (and they usually count small skits and music videos as well); and live viewers (on youtube) are very buggy and cut off a significant portion of that real number (for example, comparison between Miko’s twitch and youtube minecraft streams seem to indicate that 35% of her yt live viewers numbers are hidden [read the OP or the whole thread
>>2253454 for anons discussion on the possible reasons for it).
Reading and trying to compare all those ratios for each hour length would have been a pain for any of you, so that’s why I’ve already gone ahead and made the ranking tables, with ranks for inside each time length. The longer the stream time, the fewer vtubers that had any videos available to calculate. Never compare general view/time ratios of streamers who have very different stream duration averages - that’s why I painted those general rankings on right in grey. Only compare data (or ranks) from the same time length. .
Also, I had a cap of 43 videos per streamer, so it might miss a few videos for a few chuubas, but it’s good enough to get their ratios already. Video types like short skits, short amvs/covers/original songs, members only, or private were not included for the calculations. Videos analyzed for 'this month' are from the time period of 19-04-21 to 28-05-21 (~10pm jst). Streams from this recent weekend were not included.
You can see the biggest growth fluctuations with those vtubers who had some huge special stream (like 3ds, costumes, returns). They can be big rises if the special vids happened on this month; or big falls if the special vids occurred on last month. On those cases you can see % change of one specific time length way superior than the rest for that vtuber.
Collecting all this data was a whole lot of work, so no promises that I’ll be doing this again, or as big of a list. I don’t think I missed anyone too big, I left out the smaller nijisanjis, or holostars or whoever else because I don’t have the time to include them all - but I did include a few smaller ones just out of curiosity. If you think I left out someone relevant you can try convincing me to do their numbers as well, although if they are too small I’ll just tell you to fuck off.
