Hey Jeffrey, there are a couple of things to think about that will really improve your backspin service, I don’t think it’s far away from being a very effective serve. So first off is something that had been mentioned which is the first bounce on your side, sometimes this is far to close to the net meaning it lands straight in the net so aim for halfway up your side of the table. Second is your bat angle, you get a lot of spin because your bat is flat or even tilted upwards when you contact the ball, but often it’s not consistent, so try with a slightly less flat angle and you should definitely see improvement in consistency, when you do you can work on getting the angle for the most spin possible.
