# Bankroll units and session limits as a planning habit

Sizing play in units rather than currency turns a vague intention into a number you can check against. A unit is simply a fixed fraction of the amount set aside beforehand, and once it is defined, every later question about stake size has an arithmetic answer rather than a mood-driven one.

## What a unit is for

The unit is a bookkeeping device. It makes the size of a session comparable across games and across days, and it makes the difference between a small session and a large one visible before it happens rather than afterwards. It carries no claim about outcomes and it does not improve any wager's price.

## Deciding limits in advance

Limits set before play are decisions; limits set during play are reactions. Writing down a session length and a total amount before starting removes the need to make that judgement while the session is running, which is exactly the moment when the judgement is hardest to make well.

## What no staking pattern can do

No sequence of stake sizes changes the house edge of the underlying game. Raising stakes after a loss shortens the time to a large swing without altering the expected result; lowering them lengthens it, again without altering the expected result. Staking patterns redistribute variance. That is the whole of what they do.

## Recording rather than remembering

Memory of sessions is unreliable in a predictable direction. A short written record of amount, duration and game, kept at the time, is a far better description of what actually happened than a recollection assembled later, and it costs almost nothing to keep.
