A co-worker showed this to me. I think some might enjoy this on here.

Best I could do was 93%. 15 out of 15 in 22 sec.

OK I tried again and got up to 97% 15/15 in 17 seconds.

best so far is 98% or 99%. 15/15 in 15 and 16 sec.

Damn you

Now I'll get NOTHING done today ...

I've gotten 80% and some sweet air!

15/15 100% in 15 seconds

OK, well someones going to have to spill the beans. I can't get better than 25 seconds with or without coconuts on board.

Nevermind...got it down to 15/15 0:16 98%

15 out of 15 in 10 seconds!

It's all in the shocks....

So we came to find out that it has a lot to do with the internet connection. It is weird, with crappy signal the cart goes slow, but the time is normal.... (the wireless at work is slower than the cable, and the wireless at home is even slower)

98 %, 17 sec

I'm totally hooked on this one.

It definitely depends on the processing power of your computer. My notebook can do it in about 27-30 seconds. My workstation can do it in 10-12. Both are using the same network connection.

Got a few different designs to 14 seconds, 100%. Still haven't gotten this one to work, though...

That's hilarious.
