I've read and even followed some people's regime for arms while they work for some it doesn't for others. For someone who's been having difficulty gaining muscle in my arms I recently learned that it's the amount of time you lift and release the weight, and to do it at a reasonable slower rate and contract then those who you see doing curls as if they're in a race to beat time.

It may not be news to most, but thought I should share.

More likely in regards to flushing the muscles everyday with blood. High rep low weight sets, to avoid tissue breakdown but to allow nutrient rich blood to reach the muscle. This is an old principle a lot like double stimulation training but even more so by going everyday, then hitting a real bicep and tricep workout once a week at most. I've had success at this in bursts. But actually training arms everyday would work a lot better with biceps than triceps. Due to the majority of muscle fibers in the biceps can handle that work, the triceps not so much

Bi and tri ed is not a good idea the muscles need time to heal if you ran this routine you would just be wasting alot of your training tim also because I believe that most people already over train there arms not even realizing it because your arms are involved in alot of the exercises that you do to work other muscle groups. You would just be spinning the weels and they would not grow like you would want because there would be no recovery time.
