Question for raising my productivity

[encaprodney]

Ya, that does seem a little slow especially if you have an assistant moving things and refilling water etc.. Sometimes heavily soiled carpet needs extra scrubbing which can cut down on your hourly sq ft production and cubicles/obstacles can slow things down a bit, but even with all that you should be moving thru more quickly.
When doing bigger jobs its good to have an assistant keeping your machined topped up so that it never stops running during the job.

I don't think adding weights to your machine is the issue.
