3. Then for the second, much simpler dive I am surprised that the
results are different! I planned this very simple dive then
"standalone" in both tools -> still the same difference. VPlanner
gives you shorter deco and I really have doubts if I did <a target="_blank" href="http://s.th">s.th</a>. wrong
but I can't figure out what.<br>

<br></div></blockquote><div>I'm no German speaker, but I guess Oberflächenpause is surface interval. Can you try planning this dive again with V-Planner, but do it as a new 'mission', rather than a 5 day surface interval? In Subsurface, we ignore any previous dives >2 days earlier, but V-Planner may not, and it may be taking credit for the crushing pressure of the previous dive. </div><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote"><div bgcolor="#FFFFFF">

Finally I decided not to worry too much :-)<br>
- I prefer to see a penalty for any repetitive dive I plan so I like
the fix you did now<br>
- Subsurface at least in this examples gives similar or slightly
more conservative results -> also ok for me<br>
- My buddies and me will continue to compare different results
before we go diving<br>
- I don't do repetitive dives so often because actually I'm too lazy
to get in and out of my dry suit more than once a day + plus I'm so
hungry and thirsty after each dive that this also stops me from
doing a second one afterwards ;-)<span class="gmail-"><br>
