10x model strength not strong enough for SO or DO despite normal joint moments

Hi,
I want to compute muscle forces from running experiments with both static optimization and dynamic optimization. While the joint moments are roughly in line with the literature (see below for a comparison), I get a message that the model is not strong enough for static optimization even when I increase its strength by 10x. How is this possible/what might I be doing wrong?
Similarly, during dynamic optimization the model is not strong enough when max force is increased 2x as indicated by the muscle activation maxing out for some muscles, although the contribution of the reserve actuators is <5%. Should I in this case further increase the model's strength or can I leave it since the contribution of the reserve actuators is <5%?
