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.
