Indeed! On a related note, I am surprised nobody gave the OP a proper quiz on modern card counting. I have a few friends that have done it and it's not a profitable business any more - as I said, multiple decks with constant reshuffle, very savvy dealers and really good table observation tools make it very hard to cash in (your edge is pretty low to begin with).
Hell, nobody even scrutinized the numbers either. The OP turned 75k into 1.2m of savings over 4.5 years. That's setting aside 275 a year or so. He was also living on something, say another 50k post-tax. We are probably talking 450-500 pre-tax. I'd be challenging the possibility of taking home that much with an edge of 0.5-0.75% over the house, considering the starting capitalization. Just back of the envelope calculations, obviously
