John Mulcahy replied to the thread Same of Values" RT20 > RT30 and RT60 " or" RT30 > RT60 " ?.No. T20, T30 and Topt are RT60 estimates derived by a least squares line fit to a region of the Schroeder integral. The slope of the... -
John Mulcahy replied to the thread Same of Values" RT20 > RT30 and RT60 " or" RT30 > RT60 " ?.If you understand, why do you think there should be some fixed relationship between those 3 estimates of the same value?

John Mulcahy replied to the thread Same of Values" RT20 > RT30 and RT60 " or" RT30 > RT60 " ?.T20, T30, T60 are all RT60 values, just derived from different spans of the Schroeder integral.
