That sentence I understand
Luckily, DNA apparently doesnt discriminate between materials
BTW, James @ eVolv
advised that DNA200 uses a specific number of points, and segments in-between, to approximate TFR curve. (it wasn't said if it is linear approximation along the segment or not but I take it is)
E.g. for Ni they use 7 temp/TFR data pairs which means 6 segments. 3 of these are are more likely to used for from -100 to 70F, from 70 to 200F and from 600F to 800F or something similar.
Which means 3 segments for Ni in the effective range. Which is more than good enough for vaping purpose but definitely not the leauge where skin depht/density/specific heat etc play
Besides, and more importantly there is only a limited storage place for all the input data of all the profiles combined.
It means that you either use all the profiles with limited input data for each or only a very few with more detailed data.
Anyway, I think I will save up storage place on Ti and use two segments or even 1 if possible:
E.g:
Steam-engine uses a constant TCR of ~0.003486442 and 7 points/ 6 segments (as eVolv for NI) to define a line which is a waste of the limited storage space.
Therefore,instead of this:
-100,0.6707249584947427
0,0.8644161593801882
70,1
200,1.2517985611510791
400,1.6391809629219702
600,2.026563364692861
800,2.413945766463752
that should give a same result (if I read James well)
-100,0.6707249584947427
800,2.413945766463752
or that if I want to play it safe:
-100,0.6707249584947427
70,1
800,2.413945766463752
Too bad that this limitation renders my beloved
tables virtually useless. Tho it doesn't prevent me keep playing with them
