1. A method for lancing tissue comprising the steps of:
- selecting a desired profile from a set of alternative profiles having characteristic phases for lancet advancement and retraction;
lancing a user according to said profile using an electronic drive force generator;
determining a lancing profile trait during each of said characteristic phases;
optimizing said profile for subsequent lancing based upon said profile trait as a function of the characteristic phases for lancet advancement and retraction; and
subsequently lancing the user according to the optimized profile.
