You seem to be asking what exact percentage I used to overdose.
For the C + E brew I assumed 96% raws purity and targeted both compounds at 203 mg/ml for 406 mg/ml total, which is a 1.5% overdose. Small overdose, but it's ok for 96%+ since there is room there since it's a range, especially with 2 compounds, worse case it's actually 96% or 95% in reality, which still would be fine.
The result for Test C+E 400: Test C 196.75 mg/ml (3.08% underdose) and for Test E 191 mg/ml (5.91% underdose) (4.50% underdose total).
The result for the test C 250: 243 mg/ml (aimed at 254 mg/ml) which would be a ~ 4.33% underdose based on that result and corrolates somewhat with the result of the Test C in the Test C + E batch.
Now let's assume the Test C results are correct, that means the raws were ~ 92% purity and the raws test result was wrong, which would be possible maybe.. but not likely.
Like I mentioned both Test E and C raws were tested at 96%+. Raws look very good and homogenous, I am sure the raws purity test result is correct for the test E, it seems of very good quality, that I why I asked for a retest because it came out lower than the Test C even.
I know these results are still mostly within error margins, but Janoshik has said 2% margin for common AAS oils is more realistic.
Measuring mistake (too much oil added or something) is highly unlikely, especially with 2 separate batches.
