This is not actually my field, but I think it works like this:
osobohodina = hour worked by particular person

Example:
It takes 100 hours to build a wall. (100 hours = hours of work in total)
There are 5 workers building the wall, i.e. each of them needs to work 20 hours. (20 hours per person = 20 osobohodin)

So, in your case, the job might take 9.5 hours. If there were two workers working on it, it would make 4.75 hours per person (osobohodin).

I like odpracované hodiny, but what about 'osobohodina'? As in: 'Při výpočtu mezd členů projektového týmu je třeba počítat s
povinnými odvody zamìstnavatele za zamìstnance. Jednotkou
mzdových výdajů je tzv. osobohodina.' (not related to my translation - just found it on the www)
