Yes, you can learn more about each system and also give them a trial. Click above on MY TRACKERS, START Click the small red lettering "account/e-mail preferences" at the top left side of the screen. Scroll down and you will see: HOW MY DAILY CALORIE RANGE IS DETRMINED.
I am a returning member from a few yrs back and just noticed today while tracking calories burned and eaten today that you adjust the calorie ranges UP when we are active!!!
This was one of my biggest struggles when I was a member last. I was so numbers-driven that even though I worked out hard I wouldn't allow too much wriggle room (MY issue, I know). But for the Type A person, this is an invaluable tool!
I just want to thank whomever it was that designed this "new to me" feature. Just another positive change I have seen here at SP since rejoining!!!
