When configuring "breakSpeedMultiplier", it seems as though the client and server configurations act independently of one another. For example, a high server side multiplier with a low client side multiplier makes it so that clients can only break as fast as their local configuration dictates, rather than the server speed.

Of course, clients can manually update their speed to the server speed, but I think having the client read the server speed where applicable would be a nice QOL update.
