Formula Used
1) Field Ownership Percentage
Field Ownership % = (Entries With Athlete in Sample ÷ Sample Entries Analyzed) × 100
2) Your Exposure Percentage
Your Exposure % = (Your Entries With Athlete ÷ Your Total Entries) × 100
3) Difference vs Projection
Difference vs Projection % = Field Ownership % − Projected Ownership %
4) Exposure Edge
Exposure Edge % = Your Exposure % − Field Ownership %
5) Leverage Ratio
Leverage Ratio = Your Exposure % ÷ Field Ownership %
6) Estimated Field Rosters
Estimated Field Rosters = Full Contest Field Size × (Field Ownership % ÷ 100)

Frequently Asked Questions
1) What does ownership percentage mean in sports contests?
Ownership percentage shows how often an athlete appears across a contest field or lineup sample. Higher ownership usually means more popularity and less uniqueness.
2) Why compare field ownership with my exposure?
That comparison shows whether you are overweight, underweight, or neutral. It helps you understand risk, leverage, and how much your lineup pool differs from the crowd.
3) What is leverage ratio?
Leverage ratio divides your exposure by field ownership. A value above 1.00 means you are heavier than the field. A value below 1.00 means you are lighter.
4) Is projected ownership required?
No. It is optional. When included, the calculator measures how actual or sampled ownership differs from your projection source.
5) What sample size is best?
Larger samples are usually better because they reduce noise. Small samples can still help, but estimates may swing more from late news or lineup changes.
6) Can I use this for stacks or combinations?
Yes. Replace the athlete name with a stack, pairing, or roster construction type. The same percentage logic still works.
7) Why estimate field rosters from contest size?
It gives a practical view of how many total entries may contain the athlete. That helps you judge duplication risk and contest-wide popularity.
8) Does higher ownership always mean I should fade?
No. High ownership may still be correct if the athlete projects well. The goal is understanding trade-offs, not automatically fading popular plays.
