ITU / R-Days Block

If ITU is scheduled for the middle of the month:

Will bidding a stretch of R-Days from the 9-23rd drop the entire block? i.e. is it similar to Recurrent?

If so, confirm all of these hours go into Makeup?

I understand that any flying bid for the 1st-15th is more or less working for free. Any other suggestions to work the least for the first part of the month?

Can you provide a reference? I have found sections regarding Recurrent and R-Day blocks, but nothing specific to ITU.

Thanks,

G
