I thought people may find this shockingly interesting the way I did this week (I am always trying to tinker this)
I perform the string workout in a progressive way.
Here I took the August 18th (left) and August 19th (right) furthest out progressive string ONLY from those days and performed different variations of reducing down to 3 digits which I circled.
You will see this is VERY LIMITED SETS and ALOT OF REPEATS.
Lets check out the results of the last few days...

right off the bat at the top...
