does or has anyone ever followed and kept a record of line moves at the half...was just curious as i saw UCLA yesterday -8 and then refreshed went to 8.5 quick..and i took it and won..then also saw 96 on the total for the clippers game and refreshed went to 96.5..i took it and won again..just curious if this is a profitable system at all or just dumb luck..thx sbr's
