It seemed to me the sentence was pointed at the event at hand, my apologies if that wasn't the case.
I agreee that during RETARD alpha floor would not be available. My comment was in reply to a sentence which BTW I think was not yours.
What I meant is alpha floor is, I believe, present when it has to be, of course not during RETARD which is quite logical. The only problem with RETARD here seems to be that it happend on disagreeing RAs.
