No borrowed goals

Every score is answering a question. DN1 starts with yours.

A system for people already testing protocols, wearables, labs, training, and supplements. DN1 starts with the outcome you care about, turns what you try into personal evidence, and uses that evidence to shape tomorrow's plan.

You're already running an experiment on yourself. DN1 closes the loop.

The recovery score stopped deciding the day.

QuestionWhat should shape tomorrow's plan?

What the recovery score saidIt suggested taking it easy, but it was not enough to decide the day.

What matteredFeeling sharp at work, training consistently, and functioning well the next day.

What else was knownA chest-strap reading and how they felt both disagreed with the recovery score.

What changedKeep showing the score, but do not let it decide this day. Compare it with the next chest-strap reading and how the person feels. Follow clinician advice and stop for warning signs.

Your perception is the sensor.

You notice what no device measures: energy, mood, how you actually feel. Tell the coach in your own words instead of filling out another form.

A score has to prove it helps.

Your wearable, labs, how you feel, and your habits only matter when they help answer the question you chose. A score can be useful without being in charge.

The coach turns that into a plan.

The coach can only use what your record supports. You see the reason for each suggestion without needing to read the math.

What using DN1 looks like.

A question becomes a plan. As you follow it, DN1 keeps track of what happened so the coach can use it in the next conversation.

Coach

Why do I crash after lunch even when my sleep score looks fine?

We'll hold caffeine timing steady for seven days and watch afternoon energy, how sleepy you feel at bedtime, and whether dinner still happens as planned. One question today: did the crash start before or after lunch?

No forms. No scales. I can talk through my morning in my own words, and DN1 keeps each detail with the conversation it came from.

Selected intervention decisions from the 48-day record
Intervention	Status	Why
Magnesium glycinate 420 mg	Purpose changed	It did not improve sleep. I kept the protocol, but changed what I was checking.
Ashwagandha 300 mg bedtime	Dropped	Morning energy went flat the day after every dose. Pulled it.
Thiamax (TTFD) 200-300 mg	Kept	It kept helping even as the rest of the routine changed.
Rucks (45 lb)	Dropped	At the same pace, heart rate changed by only 0.8 bpm. I kept rucking as a steady habit and added intervals for the training effect.

The drop column is what most products will not show you. Adding to the stack is easy. Pulling something is the harder move, and it is the one that earns the trust.

“I thought walking and rucking were my cardiac base. 1,145 matched days said the real levers were weight and intensity, so the plan changed.”

On my best night of the program so far, the system told me to rest. I told it why it was wrong. It changed.

Consequence

Rest recommendations now have to name their reason. A score alone can't call the day.

Day 1 → 90

Day 1You start with the question you actually want answered

Week 2There is enough history to start the first comparison

Day 30One thing looks worth keeping and another is dropped

Day 60One result is still unclear, so the next measurement changes

Day 90Some patterns are clearer, and one question is still open

OngoingThe plan makes room for kids, travel, missed days, and stress

You're already paying for the experiment.

One wrong month of self-experimentation can cost more than DN1. Supplements, devices, lab panels, protocol time, and coach sessions are already part of the bill. The question is which parts are earning their place.

Supplement and protocol churn

Keep, drop, adjust, or test longer before the next wrong month compounds.

Devices, labs, and logs

Use them as evidence for the question you chose, not as default goals.

Coach and plan work

Keep the reason for each plan change clear from one coaching conversation to the next.

Pricing and refund terms are still being finalized. We will publish them before asking anyone to pay.
