Which base out of interest, Tontito? I was Parc in Gatwick and I still have copies of all my old rosters for tax purposes.
Out of 11 non training months I had nine days off in succession once, seven days off once, six once, five days off 6 times (so roughly half of those months). Four days off in five (just under half). This was in addition to my normal day off blocks which were usually either 3/4.
So the total days off for me in the 11 full months outside of conversion training were 164 plus 24 days leave which were contractual but didn't give entitlement to wraps. I had 188 days off in 11 months. This was Parc contract in Gatwick and this happened, I have the evidence to prove it. Now I will gladly accept that it's not a particularly realistic picture to make an ongoing decision on but I just wanted to share with you my experience as I'm surprised it is so radically different to what you are saying.
