In Stable2 we have an amplification param a and amplification precision scaling parameter A_PRECISION. a is supposed to be scaled by A_PRECISION to maintain precision in calculations, but currently, both values are set to 100. The following results in having amplification factor equal to 1 and will result in an invariant, which looks more like uniswap constant product formula and swaps may be more exposed to slippage.
The formula will have the following graph:

Make A coefficient larger, or introduce a setter to dynamically adjust the value.
