Carbs Burned by afasteryou
===========================
Track your carbohydrate usage in real time.
This field shows the cumulative grams of carbohydrates (CHO) burned during your session – tailored to your personal metabolism.
------------------------------------------------------------
HOW IT WORKS
1. Take the afasteryou Powertest (paid, online) or automatically use our Powertest AI via Garmin Sync.
Both provide your VO₂max and VLamax – essential for accurate substrate usage calculation.
2. Enter the code shown on your Garmin at:
https://afasteryou.com/connect/
3. It may take up to 10 minutes after activation before the data field updates.
Until then, a pairing code will be shown.
4. Add the field to a Running profile (uses speed) or a Cycling profile (requires power meter).
5. Start your session – carbs burned (g) will accumulate in real time.
------------------------------------------------------------
REQUIREMENTS
* Cycling – requires a paired power meter
* Running – uses speed and altitude; no power sensor needed
* The field shows a pairing code until VO2max and VLamax are set
* Works indoors as long as power (bike) or speed (run) is available
------------------------------------------------------------
DATA SYNC
* Your metabolic data (VO2max, VLamax) is synced automatically every 12 hours
* If you complete a new Powertest, updates are applied at the next sync
------------------------------------------------------------
ACCURACY
Calculations follow the metabolic model of Alois Mader (2003)
and have been validated against lab-grade gas exchange data
in cooperation with MSH Medical School Hamburg (University of Applied Sciences)
------------------------------------------------------------
WHY USE IT
* Monitor glycogen consumption in real time – essential for fueling strategies and smart pacing
* Identify intensity thresholds where carb usage accelerates
* Complements pace, heart rate, or power metrics with metabolic context
------------------------------------------------------------
UPCOMING FEATURES
* AI-based Powertest guidance for daily optimized metabolic values
------------------------------------------------------------
OTHER PRODUCTS
* **FatMax %** – shows real-time fat oxidation relative to your individual FatMax
* **Training AI** – adaptive training plans for running and cycling, synced to Garmin via Garmin Training
* **Activity AI** – advanced post-workout analysis: Fat & Carb usage, VO2max, VLamax, Training Score, CdA, muscle and blood lactate simulation

Novidades
1.2.0 — Fresh Profile Data & Cleaner Display
• Cached profile data now carries a version stamp. After an app update
the field detects the mismatch and fetches your current profile right
away instead of waiting for its next scheduled refresh.
• It keeps displaying values while that refresh runs, so there is no
gap in tracking. The new profile is picked up at your next activity
start — numbers never jump mid-ride.
• The field also re-checks for updated data during an activity. Until
now it stopped asking as soon as it had a profile to work with.
• Carbs are shown with one decimal instead of two ("78.0" instead of
"78.00") — the value was always rounded to one, only the display
carried a trailing zero.
1.1.0 — Refined Running Power Model
• Running power on gradients has been re-derived from our own platform
data: 219 outdoor runs from 184 athletes, cross-validated against two
independent running power meter families and against heart rate.
• The resulting gradient response matches the published reference curve
of Minetti et al. (2002) — our data and the literature independently
arrive at the same model, which is now what the data field uses.
• Uphill and downhill sections are now weighted by the measured energy
cost of running on a slope, rather than by lifting work alone. Carb
burn on rolling and mountainous routes is noticeably more realistic.
• Gradient is now averaged over the last 10 s of distance, making it
far more robust against barometer noise on the watch.
• Flat running is unchanged — identical values to the previous version.
• On hilly routes your numbers will differ from 1.0.0. They now match
the afasteryou web platform, which runs the same refined model.
1.0.0 — Major Update: Spline Calculation & Smarter Pairing
• Carbs are now computed via a server-fitted spline curve, so the values
match the afasteryou web platform exactly — no more rounding drift.
• Smarter pairing flow: 5 min → 10 → 20 → 40 → … re-checks after install.
• View switches from "Requesting…" to live carb tracking automatically.
• Added: D2 Mach 2/Pro, Edge Explore 2, Edge MTB, Forerunner 570,
Instinct Crossover AMOLED, Venu 4 (41/45mm), Venu X1.
0.0.8 - Added support for Garmin Edge 550, Edge 850, Forerunner 970, and Fenix 8 devices.
0.0.7 – Activity AI Integration
• Added Powertest AI via Garmin Sync – enables real-time carb tracking without a paid Powertest.
• VO₂max and VLamax are now estimated automatically from Garmin data. (HF and Power required)
• Updated pairing messages and improved background sync performance.
• Syncs every 2 min or 10 min (device-dependent); checks for new Powertest (AI) data every 24 h.
0.0.6 – Bugfix for Background Data Visibility
• Fixed an issue where the registered flag in background data was not correctly set, which could prevent the pairing code from being hidden as intended.
• This bug only affected devices capable of background data handling. All other devices were unaffected.
0.0.5 – Improved messaging and error handling
• Data field now displays “Requesting…” until a successful server connection has been made. The pairing code is shown only after the first verified platform request.
• Fixed a bug where missing speed values in running activities could cause calculation issues.
0.0.4 – Carbohydrate tracking now automatically resets to zero when a new workout begins
0.0.3 – Improved compatibility with Garmin Edge devices by extracting workout data directly from the info object within compute()
0.0.2 – Fixed bug where readiness check used an incorrect reference
0.0.1 – First release – real-time carbohydrate consumption
