If i could add my 2 cents...
You have answered your own question. Piston rings wear. In your case oil rings cannot hold the oil, compression rings don't seal properly, thus oil is drawn into combustion chamber hence the blue smoke from exhaust. Cumbustion byproducts are forced past the compression ring and into the crank case, thus smoke from the filer neck.
By adding oil during your wet test you have helped seal the compression ring and got higher numbers. That was expected. The only thing a leaked down test wil also show if you are leaking at the valves. Air out of carb,leaking intake valve. Airout exhaust, leak at exhaust valve.
