More important questions should be
What gas are you on
How much gas have you got?
Whats your SAC?
Just to put you in the picture, using my normal GF deco prifiles I use for OC diving I would be doing 5 mins deco with 1@12 and 1@9m 4@6 folowing 20mins at 29 on air.
If I did a further 12mins at 20m Id be doing 9mins of deco 1@12 1@9 6@6
So if you trying to plan a multi level deco dive on tables id use diferent tables. PADI ones are not all soft and squishy as some people might think.
If your trying to answer a PADI theoretical question then thats a difernet matter.
If not get nitrox 36% and you can do 30 at 29 and 20 at 20 and still have no deco.
