plenty of copper stops burping (and improves the finished product)

Never forget the bits of copper in the bottom of a still that isn't.
It helps.
Just sayin'

I've never used a conditioner, oil or copper and only burped once on a rum strip, is it really needed?
It may be as I run 25L in a 50L boiler.

I think you answered you own question there It burped.

Copper acts to control the boil by stopping surges caused by super-heating. It is also reacts to reduce sulphur.

IMO its MANDATORY in smart stills and HIGHLY RECOMMENDED in others (particular if they burp).
The size vs volume equation is not relevant to super-heating.

Copper coins very good. Also just a tsp of oil.
I have no problems so not going to fix.
All I wanted to point out is that you do not
have to buy expensive conditioner, there are
cheaper ways.

I could write a book on it.
And people do.
