Also I dive with a buddy using a Vr3 and we both use tables cut from proplanner cut 10%/10% but on ascent the Vr3 will sometimes skip the 15m stop, is this normal? If you decide to do the 1m stop as per runtime would you bend the Vr3? this thing is being a little of a problem as we have to do deco separately as sometime he has to stop deeper than me and I cannot wait for him due to my schedule!

If you do a slow ascent you can find that short stops disappear before you get there so it’s not unusual for this to happen. It’s giving you the option of continual ascent deco rather than 10m/min ascent and actual stops.
You can add as many stops as you like to the VR3 as long as they are below the deco ceiling it shows at that time it will not mind. If you are adding stops in the right place it will reduce the 6m stop. Use the look ahead button to see all the stop durations and depths before ascent then you can see how much reduction it gave you.

I also use a Vytec of which I find it useful, especially as a backup. Mark , did you say Vytec allows for deep stops?

It makes an attempt at it. It actually gives some deeper stops I had it prompt a 23m stop on a 58m dive but it usually it prompts 18m as the first stop and controls the deep stops with a very slow ascent rate. A normal deco dive ascent rate is 10m/min so a 1min stop every 3m is the same as a 3m/min continual ascent. The Vytec is a halfhearted attempt IMHO. The screen goes blank after 35mins at 60m because it goes outside its decompression calculations. If it allowed for the deco gasses it would be fine but it will only show the deco on the gas your breathing.
The Vytec is OK but it would appear that the people who designed it do not do deco diving so they didn’t understand the needs of the diver.
