Is there ever "never any more" ???

I agree on all counts. There's always something left on the table.
And it pushes me to wondering.... "how fast could a simple combo really go?". Somebody runs 12.50's with a car and most think it should go 12.9's, so he has done well. But what about 12.3's, is that in it? So 12.3's is reached, why not 12.10? Is a 11.99 really in that combo? By then, nobody believes it is what it is, but it actually is ... lol. So is there a stopping point? Who knows... But I do know it cost hours and hours of a person's life and some money test'n'tun'n to try and find out!
