Probability of losing 20 hands?

    I am working on my own project and came accross a problem I need some help on. Specifically, my question is:
    Let's assume a blackjack session with good rules (BJ 3:2, S17, surrender, etc.) and play perfect basic strategy so the house advantage is 0.5%. Also, the player flat bets 1 unit.​
    Based on mathematical probabilities, how many hands would normally be dealt before the player experiences his FIRST net loss of 20 units?​

    Of course to calculate how often you would lose 20 units is simply: 20/.005 = 4,000 (20 units lost every 4,000 hands)
    But that's not what I'm trying to find out. Given the fact that large fluctations in bankroll will occur during those 4,000 hands, I need to know when his FIRST net loss of 20 units would normally occur.

    Any comments or suggestions will be appreciated.
