I will also get to see if I easily get more than 4 chest per day in the focus quest.

If your win rate is around 50% and you play around 30 matches per day that makes 15 wins per day, on average.

If you play for silver chests, that makes around 7-8 silver chests per day, when you play in silver leagues. When you play in gold leagues, you will win something like 22-25 silver chests per day.

If you play for gold chests, that means 2 gold chests per day when you play in silver, and 9 gold chests per day when you play in gold.

All these are averages, based on average rshares for wins from the table shared by Splinterlands. And the average grows the higher your rating is.
