Hello ! Tell me why your 3080 tires have such a high starting force of 43 lbs. On my 3080 tires with the same dimensions it comes out to no more than 28 pounds. And the speed with such a short draw on your pistol is simply enormous. What is the secret?

Hi I made the tube loop pretty tight. The rubber tube is 100mm long and the string about 65mm. Results in a fair bit of pretension. There will also be some variation between different sources of rubber.
