You guys lost me somewhere. Mostly because I don't know the exact specifics of C1 and C2 so I am still trying to understand how this would factor into your dive count for T1. If I correctly understood the exchange above, then cave dives requiring deco-bottle + 21/35 can also be counted as T1 dives if you are counting towards qualifying for T2. If it is just towards T1 renewal, then not all of them need to be on 21.35. Some of your cave dives on 32% + deco bottle should also substitute for 21/35 cave dives?
Am I there or still shooting in the wind?
Cave 1 is basically intro to cave level. The ~60 min C1 dive at Ginnie on 32% would just begin register a deco obligation. It's the equivalent of sticking your console into the sand at 100ft and saying you are a deep diver. Cave 2 is full cave plus stage. I would say that if you are doing 1 or 2 stage dives at Ginnie and accruing 20+ minutes of deco that that should count as a Tech 1 dive.
The other aspect they were talking about was experience that should count towards preparing you for tech 2 vs a dive that should count for Tech 1 25 dive count. Using the example above, a 2 stage dive at Ginnie with 40-60 min of deco is definitely a T1 dive, but it barely breaks the 100ft depth and I would not count it in any way towards a preparation for Tech 2.
