Speed and power changes during job

I’ve looked through the docs and forum but can’t find an answer. When I’m trying new substrates, I like to change the power and speed settings while running a job (under the Move menu) until I get the desired look. Lightburn doesn’t keep track of the changes / current output so I keep track myself. Question: is each increase / decrease cumulative? Eg, if I start at 1000mm per min and press the +10%, it would change to 1100. If I press it a second time, does it add another 100 (based on my original setting) or add 110 (based on the adjusted setting)? Sorry for the long question but I can’t seem to find the answer anywhere.

We are simply sending the realtime commands to GRBL.
