How much is "a unit" in your example?
To have the same amount at risk on these three games it would be $533 so you'd still be down $1600 and you'd have bet $533 on what was very close to a coinflip (the $100 game) and only bet $533 on a game where you have a massive edge. This is the real recipe for disaster.
Also, if events happen at the same time you shouldn't be betting as much on each one as you would if they were one after the other so Kelly would actually reduce your total loss in this situation compared to flat betting.
