Having already secured wins against Leinster, Cardiff Blues and Newport Gwent Dragons, the Warriors were at it again on Friday night as they defeated Connacht 39-21.
Stuart Hogg scored a try in each half to go with efforts from DTH van der Merwe, Henry Pyrgos and Mark Bennett, sealing a second bonus-point win of the season.
And having given a number of those who impressed for Glasgow's 'A' side earlier in the week a chance - returning captain Al Kellock the leading example - Townsend admits the players should take all the credit for his rotation policy working.
"Connacht kept coming back at us and the effort we put in was fantastic," Townsend told BBC Radio Scotland.
"Connacht work really hard for one another like they've always done, but they've got more ambition and more organisation as well. They are tough to break down.
"Eight of our squad played on Monday against Edinburgh and they did well there, so they deserved an opportunity.
"We had three or four injuries from last week. We've got players that need to be rested - international players because they, rightly, can't play five games in a row.
"Our rotation system only works if people play well when selected and that's what they've since done last season.
"They blew us away sometimes with their performances and taking opportunities."
