Brushing zrc, za is not as good as brushing this

Those who haven't started, don't brush
Not on the list, don't brush
Barely on the list, don't brush
Low wear in the first 8 days, at 0.01-0.02%
Many people have already brushed over a million
Now these 3 types of people need to endure 5 times the wear to get on the edge of the list
Calculated, it's really not worth it
This is still worse than brushing zrc and ta
Unless #yala can pull up to 0.7, there's no reason for you to brush
