You all make excellent points with respect to your stances on this issue, and there are elements of correctness to them all.
As for the rise and fall of short esters in blends, I think there will always be division here, but there is also truth. Because the short ester rises and falls in advance of the long ones during less frequent injections doesn’t make it useless or senseless as some assert. Such would ONLY be the case if you were taking Prop alone. The Prop still contributes to the total dosage, as well as provides quicker results even though it diminishes (metabolizes, degrades, and is eliminated) sooner. The problem is that people generally think of Sust as being two-dimensional, making it superior to independent shorts or longs in the minds of some and inferior to others. But rarely do I see the level of examination necessary to reach the cusp of this matter.
------------------------------------------------
For example, one key often overlooked in this debate is the proportion of esters within the blend (Prop 30 mg, Phenyl 60mg, Iso 60 mg, Deca 100 mg.). You’ll immediately notice that Prop is significantly lower, whereas the mid-longs are twice as high, and the long is more than 3x as high. This ratio permits Prop (designed to release rapidly) to immediately impact the blend, BUT NOT detrimentally affect it by its relatively rapid decline...again because you’re only losing a largely insubstantial one twelfth of the total 250mgs, which has served you well and diminished…hardly a waste.
But by far the most overlooked, underappreciated, and often misunderstood element of Sust is also ironically its greatest attribute. This is the key and fundamental premise behind NOT needing to inject it as often as a traditional short, regardless of conventional usage and theory, namely the work of it’s mid-longs. I won’t go into detail, but it is these esters Iso nearer to Prop and Phenyl to Deca (also evidenced by their carbons), that meld the two together by releasing semi-short and pseudo-long dosages respectively. It is this characteristic that makes Sust strong and available from EW to EM injections, depending on the application…for which EW better suits the bb’er. For more on this see:

Of course this too will and always has been argued for and against, as is the nature of man.
But these are the facts, do with them as you will.
