Price Efficiency of Super-ST [Powers/Supers]

[AlexanderHowl]

Super-ST is an trait because it only possesses a net utility after level eight. Before level eight, it is better to purchase ST, Lifting ST, and Striking ST. Here are the equivalents:

Level 1: +1 ST plus +2 Lifting ST and +2 Striking ST [26]
Level 2: +2 ST plus +3 Lifting ST and +3 Striking ST [44]
Level 3: +3 ST plus +4 Lifting ST and +4 Striking ST [62]
Level 4: +4 ST plus +6 Lifting ST and +6 Striking ST [88]
Level 5: +5 ST plus +10 Lifting ST and +10 Striking ST [130]
Level 6: +6 ST plus +14 Lifting ST and +14 Striking ST [172]
Level 7: +7 ST plus +23 Lifting ST and +23 Striking ST [254]

My question is the following: why would anyone purchase Super-ST below 8? Is there any reason, or would it just be an exercise in futility?
