MJ Landing D/V numbers?

[Deathsoul097]

Okay, here we go: I am working on a Constellation Programme replica mission in KSP 0.23.5. As it hasn't been released yet, I am still planning at this stage. I am currently drawing up all of the D/V values I will need to pull this off, and I have hit a wall. I have all of the numbers for the transfers and propulsive braking, and I know exactly how much of everything I need, except for two of the most crucial components, the Cargo Lander and the Habitat Lander. They will be transferred to Duna in the exact same way as the DTV-Capricorn (My Copernicus MTV replica), so no problems there. The problem comes it when I need to land these completely under their own power, and I don't know how much D/V it will take to do a completely propulsive landing on Duna (The drogues would auto cut, but I will probably leave them off, as Realchutes could really disrupt MJ's accuracy on landing.) Basically, my question is this:

How much D/V will MJ use on average to land something accurately on Duna?

I would try and do this myself, but I lack the time to do it.

you will need about 1300m/s, but I would put at least 1500 for cushion.

Wait, WHAT!? Are, are you including the transfer? Because that is about double the low orbital velocity over Duna! I mean just the amount of D/V to go from LDO to landed, accurately, by MJ. Is it really that much?

It is the amount of dV given on the dV map. If you want to land accurately plan to use that much, though in reality you may only need a third of that (or even less). I don't trust mechjeb to land on any kind of body with an atmosphere, though its landing guidance is fairly accurate (if you are using stock aerodynamics)

I know it's accuracy well enough, and on Duna it is almost as accurate as on Mun, the real problem is I will have two unconventionally built landers, whose fuel flow and thrust will have to be balanced meticulously in order to work, and I need to know exact amounts. Oh well, I guess I will basically just have to make sure that it has ~700m/s then, as 1500 is definitely way too much.
