but then was shown by a very experienced and top flight instructor just how long you could take before things went to Rat !!!!!, to say the least the latter was very scary
This alarms me just a little?? How did the instructor know "just how long you can take" before things got bad?
It's not like you can push the limits until you go past the point of no return, then go "right, just a LITTLE bit quicker than THAT" - is it?
Or am i missing something? Granted I am very inexperienced so "NICE" feedback wud be welcomed!!
