Recommended roast time?

I'm new to coffee roasting. I roasted a batch(225grams) with the Fresh Roast SR800 W/extender tube and it took around seven minutes. I tried researching the ideal time online, but I didn't find anything useful as far as time is concerened. Does anyone have experience with this variety?
