Assume your friend does no more than a day a week, and in 5 years you’re worth a huge sum on money - what percentage do you think would fairly reflect his reward, that’s the percentage you should give now.
If you give 5% for example, there’s no reason you can’t give more in time based on increased input, but don’t give something you’ll regret in the future.
