I tested of work roaming depending roam-factor between R510 and R720 (both APs saw each other). APs worked under vSZ (vscg-5.0.0.0.675). For understand levels of roam-factor I used

I set strong roam-factor equal 10 in console vSZ for test. Joined to one APs and then chanjed location for signal degradation. But roaming wasn't fast. It appered only after 2-3 minutes! Situation repeated when I returned to first AP.
Situation was similar for another values roam-factor. I tested it for smartphone and laptop.
Can anybody explain me why this is happening?
