........ many schools believe that a true average flight training time for a private pilot is between 50 and 60 hours, whether the school operates under Part 61 or Part 141. Others believe that 68 to 70 hours is the more likely average. These flight hours can be spread over a time span of several months to a year or more.

I took 53 hours (part 61) over 9 months at a mom+pop FBO. I wanted to fly with the same CFI, but he bolted for another job - ended up flying with 3 CFIs at 2 different airports.

60 hours over 5 months for IR with the same CFII. 133 hours over 1 year 8 months between PPL and starting IR training

YMMV
