Everything got all f*cky last season when we tried to use that option but I might start a test league and play around with some things to see if Fantrax fixed it or not.
Hmm... I just wrote out a long post, but the more I typed, the more I started to think there was something else to the issue than I was explaining.
Let me see if I can find where we discussed the issue on here.
Nothing can be changed this season anyway... because when I accidentally changed the settings to "Weekly (Daily roster moves)" in our league, it completely changed the standings.
