I did not like to introduce this #define PRICE_LIMIT because it would
not work very well with the current function. Therefore I searched for
an appropriate function to use and got:

    val = (PRICE_LIMIT-200)+20*isqrt(x-(PRICE_LIMIT-100))

(For values x>PRICE_LIMIT and "val = x" for x<PRICE_LIMIT.)

This function gives (with PRICE_LIMIT=8700) nearly the same values as
the current function (see attached image) but is differentiable and
monotonic increasing. Additionally, modification of the parameter
(PRICE_LIMIT) does not change the gradient very much.
