You were using "No Load" testing, whereas I was talking "Loaded Condition"

AHH! So you are talking "No Load" Voltage .... so, yes, it could get a 
lot closer to the Peak value .... but NOT VERY useful!!

... and by taking into account the fact that the load drawing current 
will pull the 'smoothed' Power Supply voltage lower.
