Q1) Besides Perl from ResonantLight & RobinF125 & other Robin models, can GB4000 and Doug Coil run frequencies with more than 1 decimal point, such as 705.86, 56.56, etc.?

Q2) Also, what are the frequency range limitations of all these machine? What are the highest and lowest frequecy they can run?
(A) Perl;
(B) RobinF125;
(C) GB4000 with or without plasma light;
(D) Doug Coil

Q3) I also heard that if a machine can't run a certain frequency, we can divide or multiple it by 2 until it reaches a frequency number one's machine can run. For example, if a machine can't run freq. 5.5, we can multiple it by 2, then by 2 by 2 to reach freq. 44 so that that particular rife machine which can only run freq. over 40 can run it. Has anyone had any postive and/or negative experience on this? Please share and/or give your 2 cents. Thanks.
