Work out progressive delivery steps instantly with clear inputs, formula shown and shareable results.
Progressive delivery multiplies the traffic share at each step so exposure grows geometrically while the number of steps grows only logarithmically. Starting at one percent and tripling reaches full traffic in five steps, so a 20-minute bake per step completes in under two hours — short enough to fit a working day, which is what makes the practice sustainable.
Geometric rollout
share(k) = start x multiplier^k until the final share; steps = ceil(log(final/start) / log(multiplier)) + 1; duration = steps x bake time
Long enough for your slowest meaningful signal. If a metric aggregates over five minutes and you want a few data points, 15 to 20 minutes is the floor.
Linear steps of 10 percent give ten equal steps but spend most of the time at high exposure. Geometric steps concentrate caution where the risk is unknown.
