I like reading 5shot' s test reports. He gets right down to the nitty gritty with ' em.

If you want a graduate level course and have several hours to spare, you can pick up a lot from reading Dr Ashby' s arrow lethality study, aka the Natal Study. Yes, it' s on a traditional site but that doesn' t mean it isn' t applicable to compounds as well.
