A longer trip can carry more obligations
Adding weekdays may add work faster than it adds usable presence.
Practical relationship planning
Estimate protected time together by removing travel, work, errands, and a planning buffer from the scheduled hours across repeated visits.
PROTECTED TIME TOGETHER
Three days on a calendar do not automatically become three days together. This model starts with entered available hours per day, subtracts visit-specific travel, work, and logistical commitments, then protects a buffer for delays and decompression. It counts quantity of available time, not intimacy or relationship quality.
PROTECTED TIME TOGETHER
Protected together-hours are available capacity, not a promise that every hour will be jointly used. A lower number can still support a good visit when expectations are explicit.

CURRENT CALCULATION PROCESS
T=V[DH−(J+W+E)](1−b); ρ=100T/(VDH)
Multiply days by the hours actually treated as schedulable, subtract travel, work, and errands per visit, scale across visits, then retain only the unbuffered share.
| Symbol | Meaning | Unit | Default |
|---|---|---|---|
| V | Visits in horizon | visits | 8 |
| D | Days per visit | days/visit | 3 |
| H | Schedulable hours per day | hours/day | 16 |
| J | Travel hours | hours/visit | 8 |
| W | Work hours | hours/visit | 6 |
| E | Errand and logistics hours | hours/visit | 3 |
| b | Protection buffer | decimal | 0.10 |
| T | Protected together-time | hours | calculated |
| ρ | Time retention rate | percent | calculated |
Conversions and rounding: Convert the protection percentage to decimal after the commitment subtraction. Preserve fractional hours internally; display hours as planning quantities rather than clock appointments.
HOW TO USE
SUBJECT FUNDAMENTALS
MODEL AND FORMULA
Multiply days by the hours actually treated as schedulable, subtract travel, work, and errands per visit, scale across visits, then retain only the unbuffered share.
DEEPER DECISION ANALYSIS
Adding weekdays may add work faster than it adds usable presence.
The model reports shared capacity; discuss separately who carries the travel fatigue.
Uncommitted capacity can absorb delays, rest, solitude, or a changed plan without creating conflict.
WORKED DECISION CASES
The default schedule retains 223.2 protected hours across eight meetings after all entered deductions.
Raising work hours can reveal that a longer nominal stay offers less shared capacity than a focused weekend.
TECHNICAL LANGUAGE
EVIDENCE AND DATA LINEAGE
Keep actual arrival and departure times, work blocks, transfer duration, errands, and intentionally separate time. After a visit, compare planned and observed commitments without treating the log as surveillance.

FREQUENTLY ASKED QUESTIONS
Usually enter only waking or schedulable hours; either boundary works if it matches the purpose and is documented.
Each meeting consumes another door-to-door journey under the repeated pattern.
Yes, for a no-buffer baseline; a stress case can show how much resilience is missing.
The input is rejected because the itinerary would leave negative raw together-time.
No. It is uncommitted capacity and should remain subject to both people’s preferences.
Run each boundary separately or use the visit-comparison calculator for side-by-side cash and time.
IMPORTANT NOTE
No calculation creates entitlement to someone’s attention or presence. Plans should preserve consent, rest, privacy, work obligations, and the ability to change course.
