My home tourny structure

[The4Aces]

Is this seem wierd to anyone else? All the players at my tourny structure aggreed to this structure(usually around 12-20 people) 40 minute blind levels untill heads up play where blinds increase every 10 minutes. Blinds increase like this. .5-.10, .10-.20, .20-.40, .25-.50, 1-2, 2-4, 4-8, 5-10. Usually the game is over by then. Usually a buy in of 15 bucks (i know low compared to alot here). 3rd gets buy in back, 2nd gets 2x the buy in and first gets the rest. This seems ridiculus to me, but i have won 7 of the 10 tournamnets we have had so i dont really say anything. Does anyone else feel this is wierd? Should i bring up changing it?
