Help! How should I continue to HP wash before the removal of hpwashing?

Here is my plan

I gain 31-33 MP each time I add 1 point to mp so to reset that it would require 12mp leaving me with 19-21mp above base. With 19-21MP I can either double wash and gain only 16 HP or regular wash with AP points I have yet to get from leveling up getting me 16-20+ HP each time.
The better and cheaper option is to regular wash first.

I will try to do this till level 200 but i know i wont make it to lvl 200 b4 the legend patch.
so i will try to pump as many points to mp as possible but still leaving enough points to regular wash unless the AP reset scroll works as I hope, by moving resetting the points in str, dex, int, and luk into the unallocated pool.
Leaving 1 point in mp at the end so I can subtract any left over MP to HP(double wash).

Tell me if this is plausible.
If so I will need to solve for the optimal mix of double wash and regular wash...

I did some rough math and I think should only add 122 points to mp leaving the last 246 for regular washing at my current level

If i do so I will gain around 4420 HP where i will reach my 10khp goal
or I can double wash all my points and gain and gain much more beyond my 10k goal which is also good since you can never have too much MP
if i double wash all my current points i will get around 4800hp
a 370 hp difference for like double the cost...

any other MP I gain i can transfer to HP at the end
