TL;DR: Please DO NOT use IGT when submitting your runs. Input "Time" like always.
Hi! We've just enabled IGT timing for this game, since the mods are aiming to have frame-accurate IGTs put in for at least the top 3 digital and top 3 cartridge runs for each major category (cups will come later if they happen). I'm writing this to ask YOU as a speedrunner of this game to NOT USE the IGT field when submitting your own runs. Continue to use the "Time" field instead.
If there was a way for us to make the IGT field accessible to only mods, we would, but speedrun.com isn't very flexible when it comes to minor options like that. We're capable of deleting the IGT of any runs submitted with it, but that's a huge hassle to deal with (again largely due to speedrun.com's quirks; the process of editing single runs while trying to verify single runs is not well streamlined) and we'd prefer if everyone could help us out by simply continuing to submit only their RTA time.
The outcome of this should be that only around 6 runs per category will display IGT. This does mean that the majority of runs will not be afforded the luxury of accurate IGT comparison. This is unfortunate in some ways, but we want IGT to carry a high standard of accuracy and reliability, which is sadly impossible if we allow everyone to submit with IGT.
A brief tangent—make sure you're only submitting milliseconds if you know them accurately and input them correctly. We aren't strict with this because we know most of you are capable of doing this and it doesn't usually matter much, but there are a lot of video-less runs submitted with milliseconds that I don't feel very confident in, and even lots of runs with video that have blatantly incorrect times entered.
With all the above said, if you're interested in helping out with this timing project, please join the Discord server and direct your attention to the proper channel!
