That's a pretty scary problem to have.  Are these frequency counts or TI readings?  You wouldn't normally see two identical TI readings in a row, but if they're frequency counts, how do you know for sure you're eliminating a duplicate reading, as opposed to one that just happened to be the same as the last?

There's nothing that TimeLab can do to help with this scenario, I'm afraid.  Stable32 may be able to remove duplicate TI readings, but otherwise, yes, you'd need to write some kind of script to preprocess the sample file.
