If there have been no incidents in the past, does not mean that there won't be any incidents in the future, regardless of the great viz and the technical instructors around. Also 'very unlikely' is not 'impossible'. I never want to go to 47m without redundancy and be reliant on someone else to get me out of trouble.
Most dives go off without a hitch, but you are upping your chances of a problem going to 47m without training and without redundancy.
For example, if your buddy happens to swim 10m away (so still within your sights) and you go OOA for some reason, do you think you can swim all the way to them to signal you are OOA? I'd imagine many people would get into trouble trying to do that, like panicking. Which you do not want to happen at 47m...
If you are not bothered by the extra risk, by all means, keep doing those dives to those depths, lots of people have different tolerances for risk and as long as they are just risking themselves they can do what they want. But as you said you like to do things 'super carefully' I think you really need to reconsider the type of diving you are doing when you do not have the training and redundancy for it.
