This time comparision is for Any%. 101% re-uses a lot of the loads already seen in Any% and don't exactly need to be timed. Load times also vary, so it was better to time everything frame by frame to get a decently accurate estimate.
This also takes into account the lag (screen freezes) before the loads.

SG = "Starting Game" screen
CSL = Cutscene load (Start of cutscene)
CSE = Cutscene end, takes lag into account
HXL = Hub X load, X being the # of the hub
CP = Character pick, actually starts timing once Sparky's flipping animations are done because that's when the pre-load lag starts
RS = Race start, the moment the game loads the track
RE = Race end, the moment you "Press X to continue", takes lag into account
PL = Podium load, sometimes you skip the podium entirely so it can end when the loading screen for it ends
PE = Podium end, takes lag into account if you get the animation, if not, start of loading screen for whatever you're loading
