From what I understand, the TS code I based it on (and based on Tim Kruzel's version) only calculates the lines and does not allow for the time component. The level values are correct but not the eights values. The lookback period of 64 days for the current script changes every bar (based on the last 64 bars).
I think the original MM has a timeframe based on a fixed 0 point, and the PriceRange is based on the High-Low of the previous 64 day frame (equivalent to about 3 months). So if the Price Range for the current square should be based on the High and Low of the previous timeframe (between Oct 1, 2002 and Jan 1, 2003) - it should show the same chart as wd78.
Many people including myself dont know MM and want to have an initial idea on how it is used. l think people who know MM can show us what to look for so that we dont jump to conclusions prematurely.

BTW, thanks wd78 for pointing out the discrepancy
