Vergleich Tauchplan VPM und OSTC

[Thomas]

Hallo,

ich w?rde gerne wissen ob man mit dem OSTC an die Ergebnisse des unten angeh?ngten Plans rankommt.
(auf +- X Minuten und Meter kommt es mir nicht an, sollte nur ann?hernd m?glich sein).
Dann w?re der OSTC auch interessant f?r mich.
W?re nett wenn Ihr mir mal einen OSTC Plan posten k?nntet.

I guess this will do:

Ok, it's not from an actual OSTC, but MV log which uses the same algorithm, so the OSTC will do the same. Just enter GF low 10 GF high 85 and You get the result above which almost fits the VPM B/E +3 profile exactly.

Sound good.
Can anybody please confirm this with te OSTC.
When looking to the online manual I am not sure if it is possible to set GF LOW to 10% (recommended range 20-20%)

[Thomas]

sorry 20-30%

[sailor]

Hi, you can set the low GF on the OSTC as low as 1 ( one ).

Have not had time to try it in the OSTC yet, but setting GF low to 20 should have Your deco start at around 48m (1 bar less than what GF LO=10 would do). Changing the High level to 80 instead lands you at 92min runtime again. We dived a lot of 10/80, as well as 20/85. I have friends that always dives 10/90 and have had no problems with that either, but as we all know that depends on your current condition.
