What is your algorithm?  Here is a guess:

  - Start a timer after Emacs has been idle for 1 second
  - Do nothing while Emacs is idle
  - When an event happens, report how long Emacs was idle

The following sets an idle timer to start after Emacs has
been idle for 3 seconds.  At the next input event, it
reports how many seconds have passed since Emacs was first
idle.  ‘sit-for’ is arbitrarily set to 10000 seconds,
assuming that you only want to measure idle periods less
than that amount of time.

(defvar my-idle-time nil)

(defvar my-timer nil)

(defun report-idle-time ()
  (message "starting idle time")
  (sit-for 10000 t)
  (setq my-idle-time (current-idle-time))
  (message "idle time: %S" (time-convert my-idle-time 'integer)))

(setq my-timer (run-with-idle-timer 3 nil #'report-idle-time))
(cancel-timer my-timer)
