OK. However, I was under the impression that the whole idea of TPS was to avoid saving of tubers ..?
You will have edible tubers, however the majority of them will be marble to golf ball sized in all likelihood.

TPS is more valuable in being able to develop virus-free seed tubers, rather than to avoid saving tubers. Yes, you can get a viable crop with TPS the first year, but it won't be much that is high yielding. If you lived in an area that had 150 or more growing days, that becomes more possible, as many TPS will keep growing and bulking tubers up until the vines die back from frost. But for short season locations, you are probably better off thinking of TPS as a means to regenerate seed tuber stock that is healthy.
