What's the difference between a PB and a Score?

A PB is all of your best scores on that chart joined together.

In most games, this means joining your best score with your best lamp.

Note

Some games have some additional properties - like BP in IIDX and BMS - that also need to be joined.

Why bother?

It would suck if you could overwrite good scores with slightly worse ones, and people would NEVER agree on what the primary metric for a games was.

If you got a better lamp on a chart in BMS, and it ruined your existing sick score, that would be terrible!

Example

As an example, consider the following scores.

Score	Lamp
5000	CLEAR
4000	HARD CLEAR

Your PB on this chart would then therefore be:

Score	Lamp
5000	HARD CLEAR

As it joins the best score with the best lamp!
