If the premises are:

1. That there is only one similimum at a given time.

2. That the similumum for a given patient can change over time.

3. That remedies other than the similimum, if they are quite close can either suppress or expose the symptoms.

Then there appears to be no disagreement on the issues raised in this thread.

The question of whether near-miss remedies suppress or reveal the needed remedy is problematic.
Sometimes near remedies can stimulate the vitality to reveal the full case as nrg suggests. At other times near remedies can suppress and hide symptoms that are keys to the similimum. It's a fine line, and the latter is best avoided by not repeating suppressive remedies for the sake of suppression, mistaking it for cure.
