You are right Steve, I am quite a slow learner. Plus I am not young anymore and some motor skills are not easy to master in a short time-frame. Plus I am a bit too complex, I like to dismantle anything in pieces, understand each and every one then assemble back… as such I am expecting the instructor to do the same, down to the finest details. On top of this, I am an instructor myself (scuba diving) and I teach (and like to be taught) accordingly.
In deed if I had the chance to go back in time, I would have asked for a check ride at 15 hrs, my mistake. It appeared the bosses know exactly the value of each and every of their instructors, including mine, but waited to hear any complain 1st before deciding anything like remedial training etc. If I was the boss I would have probably done the same way. Case closed anyway.
