Well...
I couldn't let @justinedwards.jle have all the fun!
here is my implementation:

print 0, batchSize

It supports window filtering, batching, and writing the results to tags.
My work laptop is horrible and is screaming while doing this so the batching was a must. Even doing batches of 400 windows at a time is still taking upwards of 30-40 minutes per batch 
Thank you both for all of the help. I can get by doing these in small batches. It's still much faster than having to do this manually like some barbarian
) are all setup the same way and fix the outliers
