"Ramp Run" in the "Online" tab?

Just curious what the Ramp Run selection in the Online tab is for. Does it do more for you as far as analyzing the data then simply pressing "T" to freeze everything?

What the Ramp Run function does is highlight the actual cells that were used by the M1 when doing a ramp run, this makes it easier to trace the Time Graph to the Efficiency Table when you scroll back through the data after doing a ramp run.
