I just wonder why they are using 412 and 413 KHZ? Hulda Clark has 416.6 to 420.2 KHZ on her frequency list?
Stenulson has a mistake on his Hulda frequency list. Notice the middle frequency is 413 instead of the correct 418 KHZ for Herpes Zoster. Stenulsons list is all over the net. They probably used his list when designing the program.
