Ohhhh :0 that makes sense. Although if you were to use a dice roller app/program then 1d4 would be base. So rather than 1d2+1, it would be 1d4, 1d4+1, 1d4+2, 1d6+2, etc etc. (D5 are hard to come by due to the shape, and coin flips can easily be learned, I know how to get what side I want XD)
But that's just my idea on it :3
