If I set up a custom number of monthly credits, how will the credit boost be calculated?

One credit boost credit is given for every 20 credits purchased. Custom regular monthly credit purchases will be rounded to the lower whole number. So, for example, if you set up a regular monthly credit purchase of 110 credits each month you’ll receive 5 credits and if you set up 120 credits each month, 6 credits will be applied to your account as a credit boost.
