Posted by raven Posts 21 Registered at 2008-03-10 12:36:50	2008-12-14 11:18:28 - "Real" DTG
	Hi! You all know how that the DTG (and therefor also to current ranking) doesn't work perfect when rounding marks if you're not really close to the mark. Infact, in several races the leader finds himself to be ranked several hundred places down just when passing a mark. In an attempt to make that better I've made a new ranking page for the third leg of SOR and it can be found at http://sailor.raven.nu/112.html It's brand new so it might have bugs but I think it works. The distances are slighty different that the official once but not by much. It's currently generated every 15 minutes. Let me know if anything weird shows up.
Poll: How cool is it? Cool, better than the official Cool, as good as the official Waste of time Show Results (You won't be able to vote.) You need to be logged in to vote.

	Hmm...(12:16 Swe time) Im on 265th position on your leaderboard. 138 on SOL leaderboard. I think SOLs is more right. I have Santacalus behind me in the chart but in front of me on your leaderboard. It shows 691 Nm to finish line, but I meassure around 650. http://www.tangosailing.nu ______________/)_/)___________/)/)/)___ Hometown: Trosa, Sweden Boat: Albin Express, SWE 410

	Right, minor glitch It has been fixed and now reports ranking 132 (135 official) and a couple of nm less than the official DTG.

	Hi, just looked at your ranking. It's ok as long as the boats round the marks at the correct side. For example "skipper85": he is on #7xx at the official ranking, because he left Pulau We on port. You have him on #2xx.

	Thanks, nice catch! I have found the bug and skipper85 is now correctly calculated as 700-something Thanks again.

	Sorry, but i found another one: Your calculation aims at the centre of the finish line, but that is not the shortest distance to the line. so your ranking gets a bit confused now. ciao Bernd --- Last Edited by K3 at 2008-12-22 10:31:10 ---

	yes, and besides it calculates with the coordinates I've taken from the map which could be somewhat wrong. This could perhaps be fixed but not right now I also know that it has some weird things once ppl start to finish but that will be fixed.

Lago Viedma Ice Race 2025

Less than one third of the land mass of the planet is to be found in the southern hemisphere, and most of that in tropical to temperate latitudes or in Antarctica, so it is difficult to find good natural ice to race DNs anywhere in August! However, if you take an internal flight from Buenos Aires to Aeropuerto Internacional Comandante Armando Tola de El Calafate by the shores of Lago Argentino, it’s only a 100km taxi ride to Lago Viedma, where we have set out a few beacons on the ice for you for a quick 80nm blast around the four corners of the lake, and as it’s so remote here, no need to worry about breaking the solitude of monks or suffering PL!

Sinbad by Balloon 2025 - Baia de l'Oiseau to Carnarvon

How ever shall I return to report with clarity to my Great Sultan – asked Sinbad. It needs be told this island and all its fables shall be expunged from the annals of every thousand and one night. The wind howls – and sun be none (it’s Winter, Sin’bro, ed.) – and all days from the west, but let’s launch anyway and see if we can work our SOL Balloon north as the days pass aiming for Asthralaya, where The Mahabharata tells the ancients once tested mighty weapons, about a quarter and a million qasbah away (2500nm, ed.), perhaps one month.
