I believe the rule is that if it is exactly on the line that it is in fact the higher point. So on the line between 1 & 2 would count as 2 points. This is how I count it.
I double checked those figures, though, and saw that the line is actually just very slightly under the line between the two points. I triple checked on my Points Calculator (which I highly recommend) and it says 1 Point.
I bought mine at my meeting site. I believe it's about $10. I honestly think it's easier than dealing with the Points slider. Especially since sometimes the foods I've eaten have a higher fat content... or more calories Like if I'm dealing with recipes or something. Plus it fits in a pocket.
