Chart with an across the board deceleration for all branches during this month. Here are some comments

1) Hololive (the japanese branch)
Without a strong FOTM or a box game, their average went down to their resistance point, still staying ahead of the 11k line

2) HoloEN
Same as above, close to the 6.5k line

3) DEV_IS
Without any strong buff they continue their glide down, nearing the 4.5k line

4) VSPO
After an excellent March, a recline to their typical range, climbing down the 4k line

5) NijiJP
A slow glide down, having crossed the 3k line in the downward direction for the first time in this history of this chart, currently sitting in their all time minimum

6) HoloID
Same as the other Holo branches, crossed down the 2k line

7) NijiEN
Surprisingly stable but at the most undesirable point or circumstance, sitting just below the 1k line, having reached their all time low very recently

8) StarsEN
Having shed their "buffed" eventful march and Japan arc numbers, they dropped rapidly below the 1k line, the 900 line and now also the 800 line approaching their all time low in this chart

All in all: April was not kind to any of the branches with the Niji ones having reached their all time low in this chart in the past two weeks, and StarsEN getting really close to repeat that feat.
