CountUp.js version: 2.3.1

Description

When the value goes from 0 to 7240 the duration is respected
When the value goes from 7240 to 0 the animation seems longer
When the value goes from 7240 to 1 the duration is respected

You can easily try in home page
Start 0, end 7240, duration 5, the duration is really 5 seconds
Start 7240, end 0, duration 5, the actual duration seems more 7s (40% longer)
Start 7240, end 1, duration 5, the duration is really 5 seconds

I can also view this difference in my production app with lower duration (0.5s when going up is 0.7s when going down) which makes my animations not synced.
