It sounded so low I wanted to clarify and make sure you weren't describing something hypothetical (like in earlier parts of the discussion). Maybe I should have written... IS it just ONE share per TEN hours? 
...And it would have been clearer. 
...And it would have been clearer. It is just ONE share for having a lifestyle commitment to free open source development that chronically consumes at least ten hours per week/month of your time.
Even if it consumes your every waking hour that is one share - one life, dedicated to such a lifestyle. Ten hours is a minimum, surely it is very hard for such people to limit themselves to only working on the stuff ten hours, heck that is less than one day, usually when they get on a roll they are likely to very shortly notice it is morning again yet they feel like they only just woke up and got into doing some good work... When you are a lifestyle developer, it is good to try to remember to sleep at least once a week whether you need to or not.
(Ten hours is the week you go on vacation and have to work while "using the bathroom" and such because your family thinks you are actually not doing any work that week so you can spend time with them...
