Had a look for you - seems like activity is up! Recent claims are increasing and the reward pool is lower, hence the same VP will produce a slightly lower BLURT-value vote.

Admittedly that looks flat for the last month, but it takes the rpool 15 days to fully react to activity changes.
Hopefully, the recent increase in BLURT/USD prices offsets such dips :-)
