[TCML] Is tuning different for SRSG than for Static Gap?

[Brandon Garretson <garretsontech@xxxxxxxxx>]

Greetings all,
I have a question regarding the tuning of a Tesla coil that uses an
SRSG as opposed to a static gap.
Or more specifically, Is the tuning of an SRSG coil going to differ
from that of a static gap? Why is it different?
and What are some of the best methods to employ?
I have recently fitted my static gap coil with a synchronous rotary
gap, along with Freaus phase controller,
and I am using the old static electrodes as a safety gap parallel to
the new SRSG.
I have successfully tuned the device in the past (as a static gap
coil) using various methods including the Fritzs Tesla Coil Tuner (TCT
on RMCybernetics website)
as well as by scope and signal generator.
I have not been able to find specific instructions for the tuning of a
rotary gap coil other than through a “trial and error” approach.
My concerns regarding tuning this new configuration came about after
re-running some numbers through Tesla-Map 5.
It recommended increasing capacitance as well as an additional 1 – 2 turns on
the primary than if using an LTR static gap.
I have yet to take it for a test run as I am still tidying up other
odds and ends on the device but I would like to have an
understanding of why it would be tuned differently before
I power the system up and start making adjustments.
Forgive me if this has been brought up before but I was unable to find
mention of this specific subject on the Pupman site.
Or is it possible that I will just come to find that the tuning will
be the same and TM5
is just makin' stuff up?
Any input is greatly appreciated.

Thanks!
