Your unit of analysis changes
In single entry, you can evaluate one lineup. In 150-max, you also have to evaluate how the lineups behave together. A portfolio can contain many individually reasonable lineups and still be strategically fragile because they all depend on the same player, game, stack, or scenario.
Measure portfolio concentration
Player exposure relative to field ownership.
Stack and game-environment exposure.
Lineup overlap and repeated cores.
Scenario diversity — not just different player combinations.
How much of the portfolio fails when one key assumption is wrong.
Exposure caps are tools, not commandments
A fixed maximum exposure can prevent accidental concentration, but it can also suppress a real edge. The right concentration depends on the player, slate, contest, uncertainty, and quality of alternatives. Very high exposure can be rational when evidence is unusually strong.
How JARVIS uses 150-Max
Portfolio-level strategy
JARVIS is designed to compare portfolio exposure with projected field ownership, monitor overlap and stack concentration, and distinguish intentional leverage from accidental overexposure. The goal is diversified expected value — not equal exposure to everyone.
