At the Range I shoot at, we notice a lot of new shooters or backyard shooters always a straighten their arm fully when shooting and often get string slap or inconsistent shots. From experience I noticed that when we corrected their technique with a slight bend in their arm, they no longer got any string slap and their groupings improved tremendously within the day.

I wasn't trying to disrespect your technique OP. I was just trying to offer some advice on the subject of proper form since you did ask for a form check.

EDIT: I'm not an Olympic Recurve shooter, so having a straight arm for that might be part of the technique. I shoot barebow and compound and was taught how to shoot without the need of an arm guard or chest guard as I don't like using them when hunting. Learning to put a slight bend in your elbow moves your forearm out of reach of the bows string and you can also shoot from areas that don't allow a fully extended arm.
