Stage 1 chrono'd in at 330-335 fps and Stage 2 in at 375-380 fps. These results were consistent with what WGC (where I bought them) advertised that they should chrono at. I normally use a SP120 which chrono'd just prior to testing at 415-420 fps. I wish that I had bought the Stage 3 but I was unsure if I would need torque up gears.
Obviously my gun is not as perfect as Illusion's, but the Sp120 test was only 10 fps off. My G36 is upgraded with a Prometheus cylinder head, Systema NB Type 0 cylinder, Prometheus piston head w/ bearing, Guarder blue piston, metal spring guide w/bearing, Guarder nozzle, and Guarder bucking.
I say all that to ask why the Airsoft Surgeon springs would chrono so low while the other springs (PDI-series, M-series, SP-series, etc) were a consistent 10 fps less than Illusion's gun overall?

Why?

Because my gun will always be better than yours.

hehehehe.

Seriously though... given all controls were in place, it is safe to assume that springs are not manufactured exactly the same from batch to batch. Especially PDI springs... everyone knows how inconsistent those springs are from batch to batch.

Slight differences in materials used, even if the temperatures they were at when formed from molten raw materials to the cooling temperatures and time for the oil-quenched hardening will affect how the metals perform.

Because the Airsoft Surgeon springs are so new, they may still be ironing out production issues. Also, because their springs go through an extra plating process, that puts in another step which can affect how each batch of springs perform.
