I'll have to backtrack some on EOD Sustanon. Your results are pretty consistent with theory, at least when the phenylpropionate ester is assigned a half-life of only 1.5 days. In this case the oscillations are getting close in size to what's predicted for twice-weekly injections of enanthate/cypionate. However, at almost twice the frequency they are arguably closer to a normal diurnal rhythm. We might posit that with twice-weekly enanthate the longer times at alternating higher and lower serums levels are less natural and more of a problem.
Your results with enanthate are harder to understand, to the point that I'd wonder if they are repeatable—lab error, etc. A trough measurement should not be higher than other parts of the cycle.
Given your apparent sensitivity to the timing of your testosterone fluctuations I think a good protocol to test would be one that mimics a normal diurnal rhythm. This can be done by tuning a blend of propionate and a longer ester for daily injections. This may not be practical for you if you can't obtain propionate. But I do think you could learn something from such an experiment.
