3” CCVM with SPP - how fast before smearing?

[wow400]

Hi guys, how fast would a 3” CCVM with 30” of SPP go before you start to get smearing?
I’ve finally gotten around to doing a spirit run of my 40l of 40% low wines (accumulated over quite a few months from kale sugar washes).
Although I’ve done quite a few stripping runs, this was my first spirit run so was feeling my way.
Seeing as I didn’t take any cuts on my stripping runs, I took a fore’s cut of 600ml, then collected in 300ml jars for the next 3.5l. Then, hoping I was going to be near hearts, started collecting in 750ml containers for the next 8l then back down to 300ml for the next 6l. I stopped when I thought I could detect tails.

It’s all been airing for a few days so I thought I’d have a watered down (40%) try of some of the cuts - just a quick try as I’ve not had time to properly go through them all!
TBH, I couldn’t taste that much difference between any of them which makes me think I’ve smeared it all the way through.
Either that or my taste buds are shot (which is a definite possibility!).

I did a slow heat up - about 70 mins to first drips, fore’s took off at 2 drips per second rate then back into reflux for 30 mins (perhaps I need more?) then start taking the main load. Around 2.5Kw power used throughout and PC/RC cooled with mains water at about 13°c. Because I’m doing it outside and my PC is CSST, I don’t get to use the twisted pencil lead stream analogy.

Any thoughts?
