Bike ran to temperature then battered on the dyno for 10 minutes. Still finding moisture in the oil. So unless you take the bike for a good 30 minutes ride I would say you are doing more harm than good. Ran it for another 20 minutes after this to clear all the condensation
I never run mine up between using them, can’t see the point and never had a problem as long as you take them for decent length first ride when you use them again. I did start my Nsr up the other week though only because I noticed mouse damage on some connectors so I just wanted to check it still worked.
I don’t tend to run mine but wouldn’t sweat if I did. My little run around car (Schitroen c1) is often used for journeys of less than two miles (supermarket or train station runs). Mileage has tended to be sub 2500 per annum but it’s recently ticked over 100000 miles. When using in such a bad way the oil filler cap fills with thick mayonnaise as does the rocker cover (I had it off last year). Recently daughter has been using doing 100 miles plus a day. Oil is lovely and clean now! Oil is changed religiously every year regardless of mileage and car has never missed a beat (oh god, just tempted fate). Despite this I wouldn’t just start it up on the drive.
