Rate and measures of blessing varies; there is the realm of additions and there is of multiplication.
There are drizzle rate of blessing and there are torrential rates.
The determining factor is the kind of giving you engage in.
If you sow seeds, expect additions but if your expectation is multiplication, “cast your bread”.
Seeds lead to addition but sacrifice opens the door to multiplication.
You can accelerate from addition realm to multiplication, by moving from sowing seeds to casting bread. Eccl.11:1
