GPM compresses too many events
A match average combines a strong lane, safe waves, kills and late comeback gold. It does not reveal when the player crossed a specific budget threshold.
Even purchase minute is incomplete without delivery and hero position. An item in stash or on the courier has not started its economic job.
A timing needs an object of monetization
BKB, Blink or a farming item does not matter in isolation. It changes the action set: start a fight, survive spells, clear the map faster or threaten Roshan.
Name the objective before buying. If the team does the same thing after the timing and gains no space, higher net worth may not have become strategic value.
The minimum post-match scorecard
Record four points: purchase minute, delivery minute, first fight and first objective. Add the result - won, lost or never attempted.
That short timeline is more useful than ten averages. It shows where economy ended in action and where an attractive number stayed on the graph.
