Well I understand your theoretical reasoning, but often real world testing yields different results. The system isn't only keeping the coil wet it's bathing the entire atty. Could this additional variable have some impact? Maybe. But in the final wash, especially with sample to sample variances in atties, an accurate comparison/test would be impossible.The reason he says this is because it always stays wet but as longs as you keep ur atty wet it will last the same so the claim really doesn't hold much water IMO
