Most pump journals on this forum are emotional. They are beautiful. They are poetry. But they are not data.

This journal will be data. Every pump, every session, every variable — documented with scientific precision. I am tracking:

Primary metrics: Pump onset time (minutes), pump peak intensity (1-10 scale), pump duration (minutes), pump fade rate (intensity points per minute post-session).

Secondary metrics: Ambient temperature, time of day, music genre, caloric intake (previous 4 hours), hydration level, sleep quality (previous night), emotional state (pre-pump), emotional state (post-pump).

Tertiary metrics: Moon phase, barometric pressure, number of other people in gym, color of shirt worn, whether I made eye contact with anyone during the session.

I have a 47-column spreadsheet. It is color-coded. I will be posting weekly summaries with charts. After one year, I will publish a full statistical analysis. After five years, I will submit it to a journal. I have not yet decided which journal. There is no Journal of Pump Science. I may need to create one.

Day 1 data: Pump onset: 14 minutes. Peak intensity: 7.2. Duration: 31 minutes. Fade rate: 0.23/min. Temperature: 68F. Time: 6:14 AM. Music: Drum and bass. Calories: 840. Hydration: adequate. Sleep: 6.5 hours. Pre-mood: neutral. Post-mood: transcendent. Moon: waxing gibbous. Barometric: 30.12 inHg. Gym population: 4. Shirt: gray. Eye contact: once (brief, with the front desk person).

I have been following this journal for over three years. I have downloaded every weekly summary. I have built my own regression model using your data. And I need to tell you something that will either vindicate you or terrify you:

The moon phase correlation is real.

Your pump intensity peaks during the waxing gibbous phase with a statistically significant margin. p=0.03. I ran it four times because I did not believe it. It holds. The moon is affecting your pump. Or your pump is affecting the moon. Either way, the data does not lie.

The shirt color finding is also interesting but the sample size for "yellow" is too small (n=3) to draw conclusions.

I just go to the gym and lift things. I do not check the moon phase. I do not record the barometric pressure. I wear whatever shirt is clean. I do not track whether I made eye contact with the front desk person.

Am I... am I doing this wrong? Should I be tracking eye contact? Is the front desk person part of the pump?

This thread is making me question everything about how I approach this.

I knew it. I KNEW the moon was involved. Everyone told me the tertiary metrics were pointless. My wife told me I was "over-measuring reality." My therapist said the spreadsheet was "a control mechanism." But the data does not care about opinions. The data cares about truth.

The moon affects the tides. The moon affects human behavior. Why would it not affect the pump? The pump is the most fundamental human experience. Of course the moon has a say in it.

Jeff, to answer your question: you are not doing it wrong. But you are doing it incomplete. The pump without measurement is still the pump. But the pump WITH measurement is the pump plus understanding. And understanding is the next level.

I am adding "lunar distance from Earth (km)" to the spreadsheet. Column 48.
