Valentine Challange Question

Post by DarrellA » February 10th, 2023, 3:12 pm

Hi All, I was looking at the Valentine challenge honor board and I noticed that one individual had over 4 billion meters in 2 days so far. A second individual had over 2 billion and he had a little over a million meters in a year plus before the challenge started. My question is how do these people crank over so many meters is such a short time? Do they spin the flywheel with a drill or are they hacking the C2 site? The guy in 3rd has 200,000 meters. I can understand a person doing 100K 2 days in a row, not that I would but I feel that is a valid number. C2 might want to look at filtering out ridiculous distances. BTW my 19K in 2 days puts me on page 32. Lots of people with more meters in front of me :-)

Yes, I noticed that too.
It is an old problem, and it is not likely to go away.
It can be disheartening, but we need to just mostly pay attention to ourselves, or maybe the ones near us in rankings.

The good thing is that those numbers are obvious insane, and not physically possible, so it's easy to put them out of your mind.

The harder ones are the people who do say, 125k multiple days in a row. I can imagine someone with lots of time on their hands and a tough & healthy body to match doing that, but for me it would be sheer insanity. So, is it real or not?

Let's say you're rowing at a pace of 2:10 / 500m. 25k will take you 1.8 hrs

(125 / 25) x 1.8 = 9 hrs / day

Even 100k per day would be 4 x 1.8 = 7.2 hrs / day

Guys who do that almost never do it all at once, they break it down into sections, but still the part the truly amazes me is being able to do it multiple days in a row. Incredible.

A drill wouldn't work, the stroke detection of the PM5 wouldn't recognize the pattern. So at some time I guess it would stop. Or you end up with a 1000000 meter stroke. At some point the sanity checks of the PM5 will probably interfere.

Could be that people used the "Catchup Meters" function of the site. Or just added a huge row manually. Could even be for valid reasons.

A fullword field is very common in programming. 32 bits. 4 bytes.

When a fullwork field has a negative number (say minus 1) but is (incorrectly) interpreted as an unsigned number you get ---> either (32 bits 2s complement) "4,294,967,295 " or (31 bit) "2,147,483,647". Compare to the leaders ... " 4,294,967,295m" and "2,139,101,646m" I'd be looking more for faulty programming / type mismatch rather than cheats.

If it bothers you send an email to concept2. They respond and clean up rankings.

Tsnor,

Great explanation on how those super large numbers popped up. It is always better to see an attributable cause, such as an entry error, rather that hacking or cheating. I did learn that a drill wont work to inflate the numbers so with that and the 2's compliment refresher I am smarter now that when I started.

Thank you
