Commercial job made me rethink my stretch-in method for good

Did a big office space in Phoenix last Tuesday, 4,000 sq ft of commercial carpet. I always power-stretch everything, but the crew foreman told me they use a knee kicker only on the long runs to save time. I thought he was nuts, but we finished 3 hours earlier and the seams looked just as tight after a day. Now I'm torn, is speed worth ditching the power stretcher on certain jobs, or am I setting myself up for callbacks down the road? Anyone else tried this on commercial tile and regretted it or stuck with it?

Phoenix humidity is no joke, so I get why that seam looked fine after a day, but that's actually the trap. The glue and the carpet are still releasing moisture for a week or two after install, and power stretching works out that slow creep that a knee kicker just can't handle, especially on 4,000 sq ft of open floor where the substrate isn't perfectly level. I've seen commercial tile pucker at the seams three weeks later when it was only knee kicked, and that's a callback you eat with a crew for a full day, plus the client's pissed about their open space. The 3 hours you saved on that job might cost you 8 hours on a fix, and your reputation takes the hit, not the foreman's. In my experience, power stretching is worth the extra time on anything over a standard residential room, but maybe compromise on the short hallway runs where a kicker does fine. Take this with a grain of salt, but I'd rather be slow and done once than fast and doing it twice.
