I've become super lax about my additions of late - just going off guestimates and using my palate as a yardstick
Nothing wrong with that - it's how I worked out that the Tinseth calculator wasn't working for my conditions.
This is the old Excel spreadsheet I put together (about 10 years ago) it shows the interplay of the Alpha > Iso Alpha > Degradation.
Its basically equation 12 (with the sign reversed), it illustrates the conditions of the experiment, without any of the additions/modifications/improvements you have made.
Interesting work to date much appreciated.
I actually don't think the sign in Eq 12 is wrong, if it were Cdeg would move in the wrong direction over time.
As it stands the RHS of Eq 12 reads Calpha,initial + Calpha,initial / (rate terms) where any mathematician would have expressed that as
Calpha,initial ( 1 + 1 / (rate terms)).
Also at t = 0 the rate term exponentials are both = 1 so their difference = 0 and the rate terms disappear so as it stands or with your modification we would be left with C deg = C alpha, initial which makes no sense.
I believe the first Calpha,initial. term should be Cdeg,initial instead.
