Every few months, The Glucose Never Lies stops and takes stock. No single guest, no single topic: three CGM Series episodes have landed since the last round-up, Grace has a new model, and John has appeared on two podcasts that are not his own. This episode covers all of it.

Anjanee Kohli is Co-Director and Creative Director of The Glucose Never Lies® and the host for this episode. John Pemberton is founder of The Glucose Never Lies® and a paediatric diabetes dietitian at Birmingham Women's and Children's NHS Foundation Trust; he is also a person living with T1D. This episode reflects the independent views of both.

This episode covers:
- CGM Series catch-up: episodes 38, 39, and 40 in one conversation
- The IFCC glucose stress test: what it measures, the CE-versus-FDA accuracy gap, and the car crash analogy for insulin-dosing sensors
- The MDI generation gap: why people on injections have had one generation of CGM while pump users have had five
- What 17 early adopters actually reported about Night Low Predict and Glucose Predict on the Accu-Chek SmartGuide
- Grace's new model: free for people with T1D, HCP at £25 a month, Max at £60 a month, plus-one at £5 a month
- The near-bankruptcy moment: flat architecture to wiki retrieval layer, cost reduced to roughly five per cent
- Why Grace has no memory by design: the deliberate reasoning behind a deliberate constraint
- John on Diabetech (Gary Shiner's show, hosted by Justin): CGM international testing standards
- John on Tomorrow's Medicine with Arseniy Arsentyev: how Grace was built, the antibody result that started it, and what nearly ended it
- AI and healthcare work: the people who adapt, the people who hide behind procedure, and what cannot be automated
