wkend nearly gone, hope you got your chance to think and make you mind up.
I have thought and here is my conclusions:
1. you trained hard and decided to take the IR skill test
2. weather had not been clement for quite a while
3. you were building up a more and more nervousness
you knew you were ready to take it and you were going to get it done once and forever wiht a first time pass (or at least that what your mind was into). You have done it before therefore you can do it probably even better.
So I finally believe you should go for the second attempt of series 1 with the idea of getting it done. I do understand your confidence is not at its best but that is a consequence of the skill test result. This is what i believe today where i am still feeling the pressure building up.
It could also be interesting if you wrote here a detailed report of what happened. It may helps you to get a better idea and us to give a better opinion.
Catch up asap for a skinfull.
