1 entity delete = 2 Writes + 2 Writes per indexed property value + 1 Write per composite index value

Well, the OP is just another coder who can't read docs, but can write a blog.
The correct behavior would be to recalculate the indices just once, instead of reindexing after every single delete operation.
It then becomes
2*entities + 2*indexed property values + composite index values
2*entities + 2*entities*indexed property values + entities*composite index values
1 entity delete = 2 Writes + 2 Writes per indexed property value + 1 Write per composite index value
