I just used the 1450 yesterday for the first time with a starter. I didn't have a lot of activity with the starter, though I may have missed it! I added the yeast to the wort yesterday evening and there isn't a whole lot going on in there. There are some small groups of foam on the top but not covering the top of the wort. Is it a slow starter or low attenuating yeast? I made Yoopers American Amber Ale...
The answer to both questions is "not necessarily".
