These are both rather subjective conclusions of the strength and suitability of this repair. With this said, I do think this method can save many rails, and would like to see some kind of comparison test. It could be as simple as; two samples 18" long, one with the repair and one without and place them on a couple 2x4's and stand on the middle. Start with a small kid and increase the weight until failure. Dan ps, I did basically this when deciding when section size to make my seats. (I'm a big guy) "not had one come back yet." "could break that ash splint across my knee"
