Plan to spend a lot of time first narrowing down the time window of interest so it doesn't overflow its recording buffer, and then waiting for it to run at 1/10

Plan to spend a lot of time first narrowing down the time window of interest so it doesn't overflow its recording buffer, and then waiting for it to run at 1/100 speed. I used to use it. It was so painful and limited that I think it helped only a single time, and was all in all a net loss in productivity.
