You are not wrong

I know you can't totally make cuts by temperature as the guys on the other site would say very firmly, but with the pot still I can get close enough.

Heads to hearts transition is at around 85%-86 degrees for rum and 87 for sugar wash and hearts to tails is just over 5 degrees above heads to hearts, so I only need a couple of heads jars, a few small jars for heads to hearts, then move into larger for hearts and can move into large before tails start and have plenty of good feints collecting for re-run.

I can't stress enough how much the power controller has improved spirit runs already (now 5-6 hours instead of 2).

Spirit runs on the pot still, that would be
Rum or UJSSM. Small 400ml pots and borrow the
keen smell and taste budds of my daughter in
law. Have learned when she is not sure on the
transition to hearts that I want that last jar
for flavour.

As can I, with my reflux.

I continue to collect in small quantities but the same sugar wash run 30 or so times a year produces such similar results, that I sometimes don't even give a cursory sniff before blending individual botttles into a demi john.
In Pot still mode, my whisky is also not far away from automatic now. It took some effort to get the brew and feints reciever to a consistent condition, but the effort was worthwhile, regarding effort and finished product.
Life is too short to try and complicate or mystify what can be a simple procedure.

Glad to have the wisdom that comes with your experience back me up at least a little Robert.

The (piss) artists in the other place that are certain science is not possible in chemistry annoy me a lot.

Gin, rum and whiskey are a repeatable blend of art and science. Vodka is pure science.

I usually run 7/8 litres of feints watered down to 30% which probably 2/3rds fill the boiler and I come away with maybe 2ltrs at 40 % of drinkable spirit

on a spirit run on the grainfather boiler i put top switch to boil and bottom switch to mash, this geves me a quarter full power and gives an excellent slow spirit run.
