>>52613793Sparkling power doesn't affect eggs, the only way to further boost your odds with masuda method is to have a shiny charm. also level 3 egg power isn't really worth it, you're better off making great peanut butter sandwiches (1 banana, 1 peanut butter, 1 butter) for egg power 2.
The best place to hatch eggs is the zero gate, you can host picnics, no pokemon spawn there, and it's completely lagless. I like to save before i make the sandwich and wait for eggs so I can reset the game instead of manually releasing every pokemon, another helpful little tip is to use multi-select the eggs vertically to put them in your party since it's less tedious. it should take about 3 minutes for the basket to fill up with 10 eggs if you're using two cats. if you need a non-eng cat you can use one of the starter trade codes at midnight when there's less eng players, same goes for the ditto code. good luck anon.
