Could the odds not change with every F5 refresh and post added? It'd also add another way to see a draw as it drops from a hopeful 25:1 to a hopeless 180:1 within an hour. ;) I always thought that the seed was there to keep the draw honest, but with no linky script, you're left looking at all the wrong sorts of illegal and dodgy imported medications.
A random seed is just a list of useless numbers without the generator to plug them into, or an ocd mind to calculate. Obfuscation is an easy stepping stone to jump to, whether it be a random, free draw or a lucky scratch card. An easy to see, changing or static variable tends to keep everyone clued up as to how unfavorable a game of chance has become, or really is.
Maybe the waters need to be muddied to draw in the punters?
