When the tick rate is above 20 such as when using /tick sprint or /tick rate, the tick rate displayed by the infoServerTPS line is capped at 20

What actually happens is in Single Player; it can go into the 100's of ticks / second (I've seen as much as 600-800+ during a tick sprint). But, perhaps it would be more useful on a server. Without Carpet Mod, it often just hovers around 19.9 and 20.1 on a dev environment instance.

There really isn't much to gain from uncapping the 20.0 limited TPS display; besides just being able to see it rise during a tick sprint. Perhaps it could just be a config setting toggle to 'UNCAP' the limit ?
