Hello, changing the cut-offs should not have a big impact on flow since you're not changing the number of vehicles and speed limits are typically not the limiting factor at intersections. Also, by setting a deviation of 0.2 you will still get vehicles with speedFactor < 1 and those may have lower the speed overall. As mentioned, netedit does not yet support the multi-parameter version (neither editing nor display), though this is being addressed in the development version. To check the impact on your cut-offs, use tripinfo-output and then run the command python sumo/tools/output/attributeStats.py tripinfos.xml -e tripinfo -a speedFactor This will give you statistics on the assigned speedFactor values in your simulation.
