Eight doughnuts and a sleeve of Oreos, read straight off the labels, run through the estimator at Jenny's own settings. Press play and the lineup fills in as Scott and Jenny get to each one.
These are Jenny's real afternoon numbers — 1:12, sensitivity 85, target 85 — with her blood sugar set to 96 and a flat arrow. The estimator's fat-protein factor was left at 100% on this episode, so every extended figure here is the full Warsaw number, not the tool's usual 50%. 5:31
Every number is off the label at krispykreme.com. Every dose is Jenny's settings through the estimator.
Three of these went through the estimator on the recording — they're the highlighted cards, and the numbers on them are the ones Scott read out. The rest are the same settings and the same math, run afterward.
The tool wants two units up front and 0.85 stretched over three hours for the fat. Jenny would take two units flat and skip the extended — see how she does it below. Scott's counterpoint: 22 fast-hitting carbs while your algorithm has already pulled basal back is exactly when that 0.85 might matter.
A glazed doughnut in the afternoon, on her own settings.
Same doughnut shop, almost double the carbs. Over four and a half units even for Jenny — "that's also a lot of insulin at one time for me."
Jenny has watched people who don't know where to start take the total or added sugars off the label and use that number as their first pre-bolus time. She was careful on the recording: "this is not medical recommendation." It's a pattern she's seen work as a starting point, then you look at the CGM and tweak for next time.
49 carbs, 28 of them sugar. More than half of this doughnut is sugar, and the tool has no way to know how hard that first half hits.
"Like a five and a half unit bolus" at Jenny's settings, with a ten-minute pre-bolus. Jenny's own plan for six Oreos: go for a run after.
The numbers that transfer to the next doughnut.
“With only 10 grams of fat, this type of thing doesn't need an extended bolus.”
“I just don't know that our brains do the math real quick when we look at things.”
