On Question 1: At the clinic last weekend, Shaw confirmed that the two-minute time-out will not buy a player back into the game; his team still needs to take a time-out.
On Question 3, the play clock is set to 40 per 2023 Bulletin No. 1.
On Question 6, no time-out is granted per 2023 Bulletin No. 1 in 2023, although it also is not charged.
Thanks for reminding me/us about the bulletin. I should note that in my rule book (at least I should have for 2023). Perhaps the rule, itself, will be edited to reflect this for 2024, to state that consecutive
requests for a timeout will not be granted. A note like, "Note: Following a timeout requested for a replay challenge that overturns the call, the timeout is not charged to the team, but it counts as a requested timeout for the purposes of rule 3-3-4." Or something like that.
