The issue of after how many hours a stude goes solo is irrelevant. I was thirteen hours. I know some who were shorter and others who took longer, many of both groups who are better pilots than me.
In my experience, once you have your PPL and a few hours behind you, there is no correlation between hours before first solo and qualities as a pilot.
To those who are fretting about this issue - it is a complete and utter nonsense.
It is what is best for you. Even if you do not appreciate it, much of what you are learning whilst circuit bashing P/UT with a FI beside you, will be of benefit later.
