GUE goes tabular

[rjack321]

Wonder how many of those divers could realistically swim a LP95 up and remain on the surface long enough to get picked up by a boat if a wing fails?

In a Torus26! :grinbandit:

...and avoid anything AndrewG for sure.

What are they (UTD) teaching in their Open Water program (not to be confused with Rec 1)?

Yup, ironically a ~5min ascent gives you 5 more mins on the bottom

I thought Bottom Time per PADI = time from when you leave the surface until you begin your ascent (i.e. that 5 minute ascent is not considered BT).

My question is, if this becomes or is the official table for GUE, how do I order me my table? Is it for sale on their website?

GUE sent the table out by email a couple of months ago. Unfortunately the file doesn't print well, so I emailed GUE and the Rec author Jesper for a print resolution file, but never heard back ...?

I own the Rec book pdf file, and the table in there also prints poorly.

Too bad - I'd have liked to have a laminated version I could actually use.

20mins @ 100ft setpoint, air only since RTSC guidelines keep OW students <60ft anyway.

1 min over on most tables = 1 min extra ascent, shaped exponential. So if you obligate a diver to a 5min "min deco" ascent its not too big of a stretch to see how that could allow for 5 extra mins on the bottom vs. a table allowing a direct ascent. I am not sure where GUE got the table's numbers from, but they look alot like DSAT/Padi's with 5 extra mins of BT allowed due to the slower ascent

I don't know where GUE got the tables, either, but I know what Steve told me about min deco. Does anybody have a copy of DecoPlanner? Run bottom times until you get 1 minute stops from half maximal depth, and those should be the bottoms times we're seeing.

That doesn't really work. You'll never get 1min stops starting at 1/2 depth. In fact in order to get a 1min stop at 50ft from a 100ft dive in Buhlmann your bottom time will need to be way beyond recreational.

Ah, I see what you meant.

I guess, but that's only if you re-define the industry standard term "no decompression" (i.e. a direct ascent at 60fpm is always an option) to mean what we understand when using the term "min deco" (i.e. a 10fpm ascent from 1/2 the bottom level is always required at a minimum).

To me it just looks that GUE is using Navy-based NDL.

What gradient factors? 20/85 requires almost 70 minutes @ 100ft on 32% to get a 50ft stop (46min of deco on backgas).
