Having said all this, as I mentioned above I may have missed the stage 2 deadline depending on how you perceive "3 days from this email". I certainly hope that's the reason anyway,
Well I receive the email on Friday in the morning, so counted 3 days - that makes Monday in the morning. I even used my fingers.... all of Friday, all of Saturday, all of Sunday and the bit on Monday morning before the time the email was sent on Friday.
I figured the fact that pilots (and the TCX staff given the assessment for some is on Sunday) worked weekends so every day is a working day.
