Observe the full three-minute window
Three minutes provide more time to read the period, three reference numbers, colour and big-or-small category without acting on the first visual change. The next period is shown so the transition is predictable.
The dashboard corrects itself from current IST after a background tab or mobile sleep. It does not continue an outdated local counter.
Reference stability
Refreshing during the same IST period reproduces the same reference because the seed, date, interval and round are unchanged. A new signal appears only at a new boundary.
Stability within a period demonstrates deterministic operation, not predictive accuracy. The score has no percent sign and is not a win-rate claim.
Recent history has limits
The history table rebuilds earlier reference rounds from the same algorithm. It records what the site generated, not what an external game produced.
Do not interpret a repeated colour or size category as evidence that another outcome is due.
