Questions about tubes and gear that glows. FAQ

Does the ability to, apparently safely, exceed the data sheet specs by 100% have anything to do with current draw or other operating conditions? Or is this just an especially tough rectifier tube or ??? Do you think rectifier data sheets are deliberately ultra conservative in this regard?
Another rectifier, the 5AR4, has a max first cap rating of 60uF. Are there designs that safely use 120uF with this? The highest I've seen was with a Pilot 500 console amp that I restored (kind of mini version of the 232) which came with 80uF stock. I used a smaller cap when I rebuilt it.
I've always figured that going, maybe, 25% higher than a data sheet recommends would be about as far as any given rectifier should be pushed. That's just based on a vague philosophical belief not on analysis of technical data, though.
