I was somewhat surprised to read about the number of dives offered by Red Sea liveaboards.
I did back to back weeks on the Red Sea Aggressor I back in 2016. The first week was on the southern route and we did 22 dives in 5 1/2 days. This included 4 night dives. The second week was BDE and we did 22 dives in 5 1/2 days. This included 1 night dive, night dives were not allowed at Little Brother, Big Brother, or Daedalus. This trip was before the restrictions at Brothers, we were able to overnight and do 4 dives off each island.
I would find 3 dives per day disappointing. The Red Sea Aggressor IV is said to do 20-23 dives per trip:
