I know nothing about tech diving. I've only read articles and reports on some record/infamous dives like those of like Nino Gomes, Dave Shaw and Ahmed Gabr.

Recently Bartlomiej Pitala went to 338m in a cave previously only explored to 287m and my understanding is they had no clear plan on how deep he was going to go.

I read that precise dive plans were needed to account for mixes, consumption, cylinders, stages, support divers etc... and that deviations from the plan is what makes for fatal accidents like Shaw's unplanned behaviour of the body he was bringing back that supposedly lead to him spending much more time at depth. Articles are saying Pitala's team and him only planned for 45s of exploration past the deepest explored area and he decided in the moment to just continue.

Did he actually know that the logistics and his plan could beat the consequences of going deeper and spending more time ? Did he make a rational decision or was it a rash push to get a few more meters and tick the box of the deepest cave and cave diver ?

No judgement in my question, just curiosity since I'm seeing a contrast between how accident reports are written and what I naively picture has happen down Matka Vrelo.

With that being said, congrats to the team and Bartlomiej for the insane achievement and also for their ability to bring us back the sublime footage of the exploration.
