Alot of crafting results are just plain randomness so you wont get any real solid log results

ive had days without support where ill go 1000/1000 and have no issues on synths 9 levels above me
then there are those days when i go 100/1000 on synths only 2-3 above me


logic dictates that support woulda helped this, but it wouldnt

with or without support the same results would have applied(unless the synth required support, which several do)

also there is the factor of other training needed too which several people are often missing which causes bad fails, and they tend to ignore them like it doesnt matter then blame support too(ive seen it first hand)
