In the absence of experience I have always relied to two bits of wisdom.
First, never assume you know where the blockages are, so detect them and work on them.
Second have faith that the enery you send will know where to go and what to do. Your job is to work on the six keys. Especially visualizing confidently that the healing has occurred. See the healthy nail by the time you have finished. Then expect it will manifest itself, don't go checking for lack of progress.
The fungus may be the result of a habitually re-establishing blockage, so check for blockages each day, or several times a day. Don't expect to find them, but we create many of our own blockages.
Master Lin says that the Chinese see each meal as a time to heal.
You are perfection,
