Apnea tables went well last week, but I have just realised that I will make better progress if I use both CO2 and O2 based tables; this is something I learned only a couple of days back. So, I need to sit and work out the times required for the O2 tables, the CO2 being fine at present.
We have snow, and it's freezing, a good reason to move a round a lot, just to keep warm.
