i totally agree i do this to all the way to harvest you wont hurt anythingI supercrop all the way to harvest (less the final 2 weeks or so). Once they get into flower I usually do more of a pinch and roll and less bending right below bud sites... I can keep a generally tall Sativa super short and squatty by doing this. This is in a SOG.
If anything I have noticed increase in yields. I don't keep weight data around, but my eyeball is calibrated pretty good.
