I do not understand what the difference is in the DGX100's that you have different frequency listings.

X-100 strait in, will be 6.8, and so is KBS Tour S Hard stepped 1x (hs)
X-100 soft stepped once (ss) is 6.5, and so is PX 6.0 strait in, and KBS Tour S+ strait in, and C Taper stiff hard stepped once,
X-100 soft stepped twice (ssx2) is 6.2 , so is PX 6.5 Soft stepped 2x (ssx2), so is KBS C Taper stiff strait in, and so is KBS Tour S+ soft stepped 1x (ss)
You will also find the weight uncut for the shaft as Taper tip
If fitting shows that a certain cpm value will fit a specific player, 1 cpm up or down does not matter, so if target cpm is 6.8 like x-100 strait in, you have this options on THIS chart.
132 Gram - Tour X 7 ssx2 = 6.9 FCM
130 Gram - PX 7.0 SSx2 = 6.7 FCM
130 Gram - KBS Tour X = 6.7 FCM
130 Gram - X-100 = 6.8 FCM
125 Gram - KBS c-Taper S+ = 6.7 FCM
125 Gram - KBS Tour HS = 6.8 FCM
120 Gram - PX 6.0 Hs = 6.9 FCM
108 Gram - X-100 Super Light = 6.8
This chart DOES NOT say that this shafts will feel the same, or perform as the same.
Its only a chart to fit the need for e certain Cpm strength due to club speed and parameters from the players swing who adjust from club speed.

It does raise the question as to what size of a frequency window most players have (or can tell a difference with). I'm wondering if I'll notice a difference if I change my FCM about, say, .2 FCM. Or do I need to make a more drastic change to see a difference.

I'm afraid you misunderstand the purpose of the chart.Its got nothing to do with feel or ball curves, or spin and launch values for that matter.
A certain club speed makes a need for a specific over all flex, but this value is changes by the amount of cpm's necessary due to the players way to swing his clubs.
I'm using high speed camera, and playback to see what happens during transition, swing time, downswing, and release of the club. The players weight and strength, and preference for feel (soft or stiff) is also parameters for correction. The sum you end up with is used to identify shaft who meets this needs.
Then you have to go to real life testing, and try the combo Head/Shaft, and measure with a trackman to see if you got where you wanted to, and also take the players feedback for feel and wish for ball curve into consideration. The chart is just for navigating in flex and shaft weight, but nothing of the other parameters needed to find the right shaft.

My question was a selfish one in that I"m currently using X100s and am considering soft-stepping them.
If you change frequency on the same shaft by tip trim, softstepping, hardstepping or swingweight change,(not the grip trick as swingweight change)
a change of 1 cpm gives a change of 1 us feet on apex
Sofstepping once (Dynamic Gold), reduces cpm by 3, so you should get 1 yard higher apex.

I currently play the PX 5.5 straight in. Although I enjoy them, I am wondering if my ball flight is creeping up on the "high" side. Having said that, your chart shows the C-Taper R+ straight in at a FCM of 5.7. Could this .2 difference with equal shaft weight and a little different shaft design characteristics give me just that little bit of lower flight?
