Is it better to simply not offer Creator-directed finger strength testing as part of my training because it is not always successful and leaves many students frustrated?

We would not recommend throwing it out because it can be extremely valuable and a great timesaver for having a very quick feedback that is unambiguous, assuming the connection is valid, then, that takes place beyond the person. You, yourself, derived great benefit from doing this or doing it visually, but it is the same whether you use the third eye or you use the fine muscles of the fingers connected to the subconscious level of the mind. Either can give a good and accurate readout. So as you are thinking in the moment to perhaps discuss the pitfalls a bit more fully, this will help reassure the newcomers that success with the finger-testing is not an absolute requirement to achieve successful healing. That distinction cannot be over-stressed. You have made it clear—people do not have to be psychic whatsoever to use the Protocol, but to make that clear in discussing this particular function may be helpful for some, so they do not become discouraged if the answers seem contradictory or discouraging, they need not stop, but should simply move on without this particular step. It is not essential to a successful Protocol session, is only to garner some additional information along the way that is not a requisite, but is an extra bonus for those able to achieve successful communication.
