Just got 4:59.1. I can't tell whether I'm even making progress at this point.
The more I try this run, the more I realize that 4:57 will take a lot of time... or more likely, will never happen. Honestly though, the run is so short. I can't stop. If the 4:57 happens, it happens, but I am not going to kill myself over it. It's a project I will always have and may never complete.
4:57 could happen in a month, it could happen in a year, it could happen 10 or 20 years from now. It may never happen. I will keep trying until I don't enjoy doing it any more.
Just a final word about the any% run for this now:
The SDA run that was just posted is a time of 4:58.90. I won't be trying for a faster time any time soon. For me, it's just not worth it to keep trying to improve this, mainly because, I think it would take me years to actually get the time down to 4:57.
I'm 100% sure I can get a time of ~4:58.2, but I don't care to (at least not yet). To me, it would be pointless to spend months to improve my time by half a second. I'd much rather work on other projects instead. When I try to improve my time once more, I will aim for less than 4:58.
I am going to keep trying to improve any% and get that perfect 4:57 time, but I don't expect to get it, I actually don't think I will ever get it to be 100% honest.
Don't expect 4:57 for another 4+ years, at least not from me.
