Calculating odds in Stud and Stud8

do calculations of odds work the same in stud as they do in hold em?
for instance, should I be practising this:J)
for example:
stud hi (disregarding suits for now)
I have (JJ)6457,
i see villain has XXKAA2, and have a read that he has aces and kings,
aces out in other hands, my Jacks weren't out in another's hand, so I have 2 + however outs there were for the straight draw, so do I count my outs, and how many cards I've seen revealed in other hands and my own hand, then figure the odds of winning + opportunity of winning additional chips if i do improve, and call or fold depending on that?

nevermind, im playing stud8 now, and see calculating odds regularly like that would be impossible unless you are 7 of 9/ Borg.
I see you make your calls based on the size of the pot and how live you are.
For instance I just made a mistake with KK on 6th street with a gutshot straight draw, that was hardly live against someone showing what looked like a low. The pot was small and the big bet committment on 6th/7th just wasnt worth it to find out if what would likely be a single pair of kings would win half the pot or not.
turns out he had 555 and im learning.

If you are at the 5th card and know your outs, I think the rule of '4 and 2' is close enough that it can work for 7 card.
