It's what I do, as well. I always bid an unusual amount of over (usually over 60 cents)... so it'd be like 10.83, 10.63, etc etc. Because people usually bid in dollar or 50 cent marks.
However, there's eSnipe which is horrible. See a previous post in this thread where I said I don't know whether to laugh or cry... that was me capturing my bid - was going to post it as finally being mine... but then someone eSniped me.
And my victory was taken away from me in the last 4 seconds, by exactly enough to beat my bid. I am not sure how eSnipe knows the max bid - but it does. (Because at the time I bid and was winning it was 4 bids - the eSnipe came in at the 5th bid - and jumped exactly the amount needed to take me out).
