Yes, I solo'd after 6 hours (with 4 instructors), hence I didn't think it was a problem. Now after a six month layoff, I've done 2 more hours in the circuit, practiced stalls and EFATO, and am ready to solo again when the weather co-operates.
I tend to be a 'self-starter' type so I know before each lesson what I'd like to do and where I need practice, so this helps when it's an instructor who is unfamiliar with where I'm up to.
Having said that, the club keep good notes on the student explaining exactly what has been covered and what the instructor thought of my performance each time.
