benchmarks:
when i say bandersnatch or banderwagon - i mean an MSM with bandersnatch or banderwagon group. There are benchmarks for bandersnatch in https://github.com/zhenfeizhang/bandersnatch:

bandersnatch:
cs for base var: 5
cs for scalar var: 256
cs for mul : 2869
cs for result var : 27
cs for equality : 20
total constraints : 3177

jubjub:
cs for base var: 21
cs for scalar var: 256
cs for mul : 3325
cs for result var : 21
cs for equality : 2

bandersnatch with the glv:
cs for setup: 16
cs for endomorphism var: 6
cs for scalar decomposition var: 405
cs for msm: 2176
cs for result var : 16
cs for equality : 2
total constraints : 2621

These benchmarks are generated using arkworks tool for generating r1cs contraints - I'm not sure about the exact spec of the benchmark, would need to dig into the repo or ask author directly about these

But still there is no benchmarks for banderwagon - maybe i'll work on that but first need to get better understanding of it (banderwagon)
