10% Cuts Off 10% or off total 100%?

Hello. I just started my taper last week. I’m on .5mg of clonazepam. I have a scale and I started to shave off 10% of my morning dose everyday. Going forward, the next time that I go down, do I shave off 10% off of what I am currently taking or same amount that I shaved off the first time which would be another 10% of the original total weight of the pill? Or does it not matter?

 

For example: If I had 100g, I would shave off to make it 90, then 80, 70, 60, 50, 40 and so on.

 

Or

 

If I had 100g, I would shave off to make it 90, then 81, 72.9, 65.61, 59.05, 53.15 and so on.

Ten percent of the most recent dose. Not ten percent of the original dose.

Rebecca gave you the right answer. However, if you want to understand why, here is a video from a psychiatrist explaining the idea:

Ok thank you both.
