There is a point at which service aggression is just right to achieve the highest point scoring (breakpoint) percentage, but it varies.
A fellow blogger took a look at scoring points in streaks in the volleyball and how it relates to the outcome of sets. I have my thoughts on the subject.

In the 2016 men's NCAA volleyball finals it looked like a conservative serving strategy ended up backfiring pretty badly.
A funny post by a fellow blogger on the subject of service target zones comes as I am considering my own usage of them with my team.
Lots of volleyball coaches want their teams to serve tougher, but there's a trade off between winning more rallies and losing more points through higher errors.
