That link just takes me to a blank page Gary.

It all sounds very good though...lol

Dave, I think it's a problem with your computer. I've tested it with Win 7, Win XP, Linux, iOS with IE8, Firefox, Opera, Google Chrome, Safari and Acrobat, Foxit and whatever Apple use to read PDFs!

The most likely problem is that the link between your browser and PDF viewer is broken. Try downloading the file to your PC then opening it locally. The solution is probably to un-install and re-install your PDF reader.

For anyone that can't be bothered to go back to page 1, here's the link again:

Yeah, it works when I download it Gary, thanks. My comp has always been a bit odd about PDFs.
It's looking good, I've followed it through and seems ok. Think I'll print a few off and do a test draw/run through, check that it works, and also that I understand it, haha.

Gary, what happens when we get to the "finals" section of the competition? Those group sets would get us up to the top 8 robots, I believe, of which 4 will have 2 lives remaining and 4 will only have one.
I'm guessing it pretty much speaks for itself at that stage of the competition. I think I'm right here:
- the 4 with the 2 lives left fight each other in 2 fights, leaving 2 with 2 lives and 2 with 1
- the 4 with only one life fight each other in 2 fights, leaving 2 with one life and 2 out
- the 4 with 1 life left fight each other in 2 fights, leaving 2 with 1 life and 2 out.
This leaves 4 robots, 2 with 2 lives and 2 with 1.
- the 2 with 2 lives fight each other, leaving 1 with 2 lives and one with 1.
- the 2 with 1 life fight each other, leaving 1 with 1 and 1 out.
- the 2 with 1 life fight each other, leaving 1 with 1 and 1 out.
- the final is between the one remaining one-lifer and the 2-lifer.

Of course, this works much better in practice than written down

But I think I'm right, if you can follow it.

That's far too complicated to try to follow at this time of the morning! (Although it sounds plausible.) But never fear, Mr Waller has charts to cope with finals for 2, 4, 8 and even 16 groups!
I think the spreadsheet currently implements the more common 4- and 8-group versions.
When Modelworld is out of the way I will get the remaining new sheets sorted out and send them to Peter. I will also update the spreadsheet so that it follows the new charts properly. Then I think we'll be ready to go!

Sounds about right dave, but its still too early. I can't handle my beer like I used too...

This picture also looks ok, but remember the final can happen twice.

Remote-Controlled Dave · Sat Feb 19, 2011 11:18 am

Yeah, one robot having to beat the other one twice to win is the only thing I don't like about double elimination, but its the only fair way of doing it, so game on.

I think, when I get down to this final stage, with the winners and 2nd placers from each group, I will do another quick draw, just to keep things interesting.

mixing up the winners braket and mixing up the loosers separatly?

Yeah the having to beat them twice is annoying, but if someone wins all the way through to the final to fight a robot that has already lost one it makes sense. I am too lazy to look up previous results, but has there been a case of the 'bot who has lost one' beating the 'bot who has not lost' first then lost in the second fight?
