    Yes, the same.

    No 100 bottle , but the same applies to the 120 bottle.

    If the shcedule says 30 minutes, 30 minuts is the time no matter
what gas yo are breathing - you do not add more time to take a break.
This would add hours to a long dive if you did.

  No mod at all , but for cold, I would shorten the BT and the deco
since you are wasting your time decompressing once you are cold.
