Hi motorpsycho
For your answer you need to look at emissions regulations.
If the government stipulates an emissions regulation that works out to be 50:1, the manufacturers will all recomend 50:1
Manufacturers must then use methods of giving the consumer reliability by new metals technology and cylinder plating technology and a further option of simply detuning their engines to give the required reliability.
Nikasil plating technology came into widespread use when emissions regulations dictated the move to 40:1 oil/fuel ratios.
Unfortunately our cheap and nasty Chinese Bicycle Engines use a very poor quality version of a chrome plated cylinder bore and the metal used in the casting process is also bottom of the barrel in respect to quality.
You can still use lean oil/fuel ratios with a well designed cylinder structure made from high grade alloy and a laser etched chrome plated cylinder bore - naturally the price reflects the technology.
At the end of the day, rather than asking the question "who is right, who is wrong", it's only a simple matter of spending 3 or 4 weeks doing some serious and intensive research to find a definitive answer - basically, start opening a lot of books, give yourself the opportunity to spend time in a large library researching the topic and use the internet for any out of date scientific publications.
Military defence research papers are another good source of information as their requirements are not bound to civil emissions regulations - they need a product to work as well as it can.
You have the power to fill your head with well researched knowledge - a little intellectual fortitude goes a long way to providing answers.
