Hi, I am doing the following co2 table daily:

breath 2:00, hold 1:20, breath 1:45 hold 1:20 all the way to breath 0:15 hold 1:20 (total 8)

I have a few questions on it:
1) the breathing between holds, should I try to breath normally or is it ok to do recovery breathing in that period?
2) last breath before the hold, should I take as deep as possible , full lungs?
3) sometimes instead of construction I feel like a shivering going through my body, is that normal?
4) I only start to feel the heat in my core around the 7 round, does it mean I should increase the hold time?

thank you to anyone who will contribute from their knowledge
