The problem here is that you can't realistically sample a curve off the
three lowest points... Not enough data and variance and such. Anyways,
making another equation is possible, but not necessary. The really really
fast way to do it (which is always best for a mud) is to make a 100-element
array that contains the total amount of xp needed to level. Change the
xp-finding function into a simple lookup function xp_needed(x) = table[x],
and add a startup function that initializes the table.
table[0] = equation(0); // here equation() is the original
eq.
for (n = 1; n < 100; n++) {
table[n] = equation(n) + table[n - 1];
};
