Engagement per user is 12m 25s.
game_board takes up 90.4% of total engagement, however average engagement time is only 0m 54s for the game_board .
How should I interpret the numbers?
(avg engagement time x avg engagement count) / 12m 54s = 0.904 for game_board?
回答1:
That the average user spends 54 seconds playing something until game over/exit game. One session can have multiple user engagements, i.e. the user restarts the level after game over.
The average user spends 12m 25s in the app, with 90.4% of that time spent on the game_board.
