Symon refresh rate extremely high

I want to slow down the symon refresh rate but it only goes higher no matter what value I give symon-refresh-rate. Even the default value 4 updates the values hundreds of times per second. I'm on Emacs 27.1.

`(use-package symon
  :ensure t
  :init
  (setq symon-refresh-rate 1)
  (setq symon-delay 2)
  (setq symon-sparkline-type 'plain)
  (symon-mode)
  :bind
  ("M-s-h" . symon-mode))`
