Losing 27 blackjack hands in a row

[RiverTheNuts]

I get the odds to be ..49^27

This just happened to me on party, and using between 5 and 25 dollar bets I just lost 400 dollars.... I got a few ties in there, like when I double my 11 to the dealers 6, get a 6, and the dealer flips an ace, this happened at least 4 or 5 times, which was better than the under card always being a 5 and the facecard always coming when I had 20

.49^27 = .00000043% or 1 in 231 million ... Sweet, is this the right calculation more or less, or do ties have something to do with it
