If you'd like a web-based resource for IGT splits, use this tool: https://grun1.com/utils/timeCalc.html or https://djungman.github.io/timeCalculator/ (allows you to just type numbers and autoconverts to m:s.mss) during your run for in-game time summation. This works if you prefer it over livesplit (or would like to run an RTA timer on livesplit for viewers to see). Pressing tab on field 1 automatically goes to field 2, so you don't have to click on the site during your run; just play track -> enter time -> tab -> play next track!
