I wouldn't worry about the shutter count too much. I don't use the 256 option in the SR much at all. I usually just stick to 16 through 48.
Here is some info from Fred on FM

Fred - any guidelines from your experience in using this app?
I only use the 'custom setting' and my default is 16 shots. I never use this app with fast shutter speeds as the 'smoothing' tends to be choppier. So, my rule of thumb is to keep a minimal of 1/50s shutter speed. If that's not possible, I use real ND filters in combination with SR.
Very important: Expose your image to the highlights!! Even though the resulting image is RAW, it does not have the same highlight latitude as a regular RAW. Since SR will improve SNR and random noise tremendously, this is never an issue. Use Zebra 100+ as your reference. If you see the Zebra pattern in areas of your image, lower exposure until it's gone.
Do not use the ETTR Zebra technique with SR. It will ruin your shots.
If I have to underexposed the image considerably (like 2 or 3 stops) I use more images like 32, 48 or even 64.
I try avoiding 64 or 256 images unless drastically underexposing my images because the shadows will be so clean, it may create posterization in solid areas. Adding a little noise in post to dither takes care of that though. You may think I'm crazy underexposing my images 3+ stops....Well, it's not a problem with SR as it will give you super clean shadows when recovered in post. It's actually quite amazing.

Here are a few examples. Pay attention to the Shutter speed and Exposure compensation:
