[Thief] Question regarding HP Washing and related technical discussions

So, I'm making a bandit and I'm interested in that sweet HP gain from washing. ( thinking of PB )

I got 60 base INT since I was lvl 20ish and was able to get to lvl 50 with these stats :
HP 1683 / MP 1231
( Haven't done any HP Washing atm, just increasing MP )

That means that at lvl 50 I would have :
Base MP = 14 * 50 + 148 = 848
Meaning I have 1231 - 848 = 383 MP Extra

I'm aiming for lvl 120 with 5k+ HP.
Here's a copy-paste of what I wrote on discord for myself :

At lvl 120 a thief has 3.083hp:
With 3 washes available per lvl from lvl 50 you can get 120-50 = 70*3 = 210 washes;
210 washes * 12 = 2.520hp ;
Meaning you have 3083+2520 = 5.603hp;

But that's 651.000NX, so 130 days voting at 5k per day;
Not counting the bonus 1k you get from consecutive voting.​

This is my goal for lvl 120.

Now I gotta ask, given that I only washed for the first time on a warrior, it was specific as it had HP Increase skill and was better to just push all APs into HP then wash out MP to STR/DEX/INT.

Does it work the same for Thief?
Or are there better ways?

I'm thinking of MP washing too, I'm thinking of getting like 160+ base INT at lvl 80 so I can get that, and this is what I found on an early thread on MP Washing :

So it means that I'm able of getting [(160/10) -2] more int per MP Wash.
So I'd be able to get more washes per level.

Is this way correct for a thief?
How should I do it well, like a warrior push all into HP then wash from MP, or are there other ways?

Any technical discussion and comment I would really appreciate, as I've not noted that HP washing on other classes was this painful ( ez warrior life )


pls don't hate on me for washing a bandit, ik it's dumb but don't be a cuntlord that says
"but you have mezogurd huhuehue xd jkjk lulul"

 

Seems easy then.
What about the Washing.... is it like a Warrior?

Drop APs into HP then wash out of MP, or some other stuff?
Like MP Washing to HP Washing?
