it would be nice if the hits you were no longer entitled to do would somehow disappear from the hit list so you wouldn't keep clicking on the same hit and wasting time.
Yeah I'm afraid of clearing out any history on my browser, because if I do then the links won't be purple for the ones I've already done.
You can make a spreadsheet in Excel and then search it before you accept a hit. I wish there was a better way, though.
