Site Feature Notes

• The graphing function has two "hidden" features - you can pass how many updates you want graphed by setting "&max=N" in the URL(e.g., for the first 10 updates, &max=10), as well as the desired time difference between updates in seconds (e.g., 300 seconds for 5 minute updates, &seconds=300). For instance, to see the first 30 15 minute updates for Link vs. Cloud 2K6, set &seconds=900&max=30 in the URL

User NGamer has created a website for x-stats.

User RPGuy96 has created an Extrapolated Standings Calculator—a downloadable tool that can be used to estimate the results of hypothetical match-ups based on past data. To use it, you will need the Java Runtime Environment.
