High Voltage electrolytics- how much current leakage
at rated voltage is "too much?"

There are old standards published 70 years ago,
but I'm interested in your current insight.
Say- I have an original can capacitor, 
rated 40-40-40 at 450 volts.  
After sitting with all three tied together and at
400 volts, total leakage was about 1.5. mA.

I'm not interested in re-igniting the nasty name-calling
over whether or not "re-forming" caps is a good 
or bad idea- only in what level of leakage is, in your opinion,
acceptable in order to maintain a stock part in a set.
