Simple answer... you can't. There is an Appendix in R56 that details how you
measure your system to insure you meet whatever standard you set for yourself.
It would appear that the equipment for the measurements is more expensive than
adding a significant number of rods and wire. I'm planning to create the
largest disc-like field possible within the bounds of my tiny property, which
according to my figures will be massive overkill... which is exactly what I am
going for.
Please feel free to email/call me if you want to chat on the subject. I have
spent several hundred hours researching, studying, designing my system.
I'll guarantee you that there are folks here more experienced and more
qualified than I to discuss this with you, but I'm willing nonetheless.
Have a great day!

I’m laying out the ground rod scheme for the towers.
As I look at Mot R56, it seems like about 45’ of rods gets you to the 5 ohm
target based on one of the graphics they provide That’s about 9 ground rods
spread out in 3 legs each with 3 rods separated by 16’ assuming 8’ rods and
average soil.
While I realize more is better, how do you determine “enough” in the context
of ground rod count?
