Finicky to say the least

Not a bad idea for an app. I thought it would be quite funny. However, most people that try it just get angry since it is so hard to get an actual reading. Why is it that one time I can punch a 140 then the next 10 times I get between 0 and 50??? There needs to be some sort of buffer so your backswing doesnt register for your actual punch...
