Two Guettler diagrams illustrating the theoretical limits for achieving “perfect” attacks. The solid lines represent the boundaries (conditions A–D) formulated by Guettler [11]. The bow acceleration should be maintained lower than both A and D, and higher than B and C. The influence of β is evident when comparing the two plots. For a smaller β (closer to the bridge), conditions B and D define the more stringent limitations for bow parameters. Conversely, for a larger β (further away from the bridge), conditions C and A become the more restrictive boundaries. The exact point at which these roles switch depends on the specific ratio between the dynamic and static friction coefficients.
