Ok this has to be out on this board some place but here we go...I've been following WW home since January and have lost about 50lbs. I am a 100+-er so don't be TOO impressed

I have been hand writing everything I eat and recently was given a WW Point calculator that is a few years old. I have a question...
Here is the scenario. Lets say I work in the garden (low level activity for 30 mins). That shows as 2 pts. If I do that 5x then I have 10 pts but when I ask to convert the "10" or whatever number I have (7 may be max - can't recall) I wind up receiving more points than the actual 7 - HUH????
Can someone shed some light for me? I am losing it
