Hay Penyu,
By nature i am not the type to take it slow, at first i was getting PB's on every dive session untill i hit 44m and left dahab.
But then i moved to Thailand and to the the Philippines where i was limited to around 30m depth and have been to this date. i will be in dahab for 2 months starting mid july so that will be my first chance to see how the slow approach trance-fares to depth.
So i cant answer for my improvements in dive times/depth at this moment. What i can talk about is the change in attitude that has occurred. Knowing the levels of relaxation i have attained doing 30m has taught me the futility of putting new pb's before relaxation, so automatically I'm not going to progress to a deeper dive untill my current depth can be done without any negative feelings.
Also by experimenting with shorter breath holds and concentrating on reducing my contractions i have realised that you can put off or stop them, so now if i do feel them on a dive i take it as a sign that i'm not as calm or focused as i could be. were as before i would think, "oh no now they'v started" as i if was a victim of these contractions and they will automatically get worse and worse.
Knowing i can do the dive easily also allows me to concentrate on other things such as muscular and especially stomach/diaphragm relaxation or mouthfill. If a dive is tough then that is not the time to be trying new things, these things should be drilled into you during easier dives.
Right now i feel like this time has change me for the better as a freediver, for example, I remember one panicked, rushed cnf dive to 25m that i did in the beginning that left me hypoxic, now i do no warm up, half lung cnf dives to 30m without a contraction and totally relaxed.
I'll let you know how it all goes after dahab
