IO540,
sorry, I wasn't trying to pin you down to an exact figure. At the end of the day, that really comes down to the blend of individual skill, experience and the aircraft. However, I am aware that some pilots only manage the 12 hours required to keep their ppl and even just for VFR I feel this is too little.
When are you planning on the IR? Have you used your IMC much in the meantime?
Cheers
