Mine has a little smiley face. I believe the internet would say my pH meter is “wholesome.” 
Maybe! Or maybe just taking one for the team.
FYI – it STILL works just fine. Haven’t busted a probe yet.
One case where I can state that correlation indeed does imply causation is for the case wherein since I started wearing my garlic necklace I have never been attacked by werewolves or vampires. Er, wait a minute… Perhaps I need to rethink that… ;D 
:o
I dance naked in my yard in a counter clockwise direction to keep elephants away. Haven’t seen one yet, so it must be working.
Hmm I don’t do any of that, and have no elephants.
Well, things just fell off a cliff there.
Regarding pH meter care, any idea how measuring hot wort is relative to letting your probe dry out?
That’s because they only come out at night.
Exactly my point!
They could also be invisible. Which brings me to: “If you’ve seen one invisible elephant, you’ve seen them all.”
But joking aside, the point Denny is making is that correlation does not imply causation.
This is important. One of the things that happens with software at scale is that the more users you try and tailor it to, the less effective it starts to get.
The most accurate and useful software? Usually a spreadsheet made for one user. It is tailored specifically to the process and brewhouse of one person. Say you know 10 people who brew roughly the same as you. It will still be accurate to a point, as each brewer may require certain tweaks that affect the overall accuracy of the individual but yield solid results for the group.
Now go to 100. 1000. 10,000 even. You end up diluting things and generalizing to the point where people accept things will just be “in the ballpark”. I’ve gone back to just making sheets for the folks over at the LOB forum and only because there is a smaller pool of people and the spreadsheets stay consistent across the small group and the low levels of variance between ingredients, process, etc.
I don’t envy those have to have to market and sell their software products (in any sector) to a large number of people because it is generally hard to please everybody, and in brewing in particular, nearly impossible to keep things to everyone’s liking the more users there are.
Hey, I like that corollary!
Well then, thank you for your service!
Glad to help…happy you don’t have to see it! ;D
