There's no static schedule. It's an e-ink display. Refreshes happen when software tells it to display something new and take several hundred millis per blank - and a screen can be up to three blanks (because if it doesn't go white-black-display, then some pixels get stuck "on" or "off" or "halfway").

In that case, it’s clear that eliminating the network request before triggering the refresh directly reduces the amount of time the user has to wait to see the result.
