Rediculously small sample size for any meaningful interpretation. Keep putting your money in when you're way ahead. It will pay off in the long term. If the variance is hurting you too bad, drop to lower stakes or go ahead and let them see the flop. The thing is, if they're going to fold because they don't hit the flop but would have called all-in preflop, the majority of the time (over the long term!) you're costing yourself money.
