(baseInterval time.Duration, elapsed time.Duration)

// The interval starts at baseInterval and increases to
// a maximum of baseInterval * 16 over time.
func GetProgressiveInterval(baseInterval time.Duration, elapsed time.Duration) time.Duration {
	switch {
	case elapsed < 60*time.Second:
		return baseInterval // 500ms for first 60 seconds
	case elapsed < 2*time.Minute:
		return baseInterval * 2 // 1s for next 1 minute
	case elapsed < 5*time.Minute:
		return baseInterval * 4 // 2s for next 3 minutes
	case elapsed < 10*time.Minute:
		return baseInterval * 8 // 4s for next 5 minutes
	default:
		return baseInterval * 16 // 8s after 10 minutes
