Multiplikation are slower than shifts.
And what is it with ((maxPoints<<1)+maxPoints)<<2 ) or maxPoints*3 :-)

Ah, nice trick

Well that was true for some CPUs a long time ago. Both the javac compiler, the runtime and even the CPU will recognize what *2 or /2 means and use the most efficient way. Use the one that is more readable for humans and the compiler will handle it.
