Back in the old days an RPPL required a minimum of 3 hrs IF training, and a PPL required an additional min. 2 hrs IF training - for a total of min. 5 hrs for the PPL.
Was that enough for a low time non-instrument rated PPL who had flown into IMC to get themselves safely out of the ****?
Well it was for this one!
And then some bright bunny thought it would be a good idea to reduce the requirement.
