That does not sound too bad but it is possible a finger cannot apply enough force. Have you ever used a wood router by hand so you know what kind of force you need to exert to push it through a piece of wood at a decent speed? My guess is that it can be up to twenty or thirty pounds, or more in some cases. I doubt whether you are exerting thirty pounds with one finger.
That said your stiffness may be quite okay for wood working where +/-0.01" can be quite adequate.
An open mind is a virtue...so long as all the common sense has not leaked out.
