It might be worthwhile noting that Heavenly Chips is the only game mechanic that ramps up exponentially. All other things being equal: bonuses, run time, the amount of heavenly chips you get on a reset is proportional to the square root of amount of heavely chips you already have. The square root slows down the growth, but does not change the fact that it is exponential.
This means that at the limit, if you reset every day you can expect the maximum cookies you reach at reset to increase at a constant (if slow) rate.
