Key Checkpoints in MKPC Tracks

I was wondering if there was any way to view the key checkpoints on tracks (Mainly vanilla tracks, not custom ones).  The reason for this is that many times I have experienced problems with key checkpoint boxes on some tracks.  For example, on Ribbon Road or Lakeside Park, if you take one of the jumps too tightly, cutting off a bit of track, there is a chance you will miss the key checkpoint box and not get a lap count.  This is annoying enough while trying to get a decent time of Time Trials, but even more annoying when I lose hundreds of points online.  Does anyone know if there is a solution?

I can't think of a solution, but you're not alone. I've had similar problems on Airship Fortress. If you are wondering how, the world record for AF goes OoB on the part with the Rocky Wrenches. When trying to Time Trial AF, I tried it, and multiple times I went too tight and missed a key checkpoint.
That's one of the reasons why I dislike this game's version of AF.

One of the things that gets on my nerves is that on some tracks (like Riverside Park, Bowser's Castle 2, Broken Pier, and Yoshi's Desert), you can use OoB to cut off huge sections of track while still getting a lap count.  Meanwhile, on Ribbon Road, Airship Fortress, Lakeside Park, and a few others, just barely clipping OoB or even just jumping over Oob can cause you to lose your lap count.

True, but once you learn where the checkpoints actually are, the OoB cuts can be actually useful.
To learn, just watch the world records for the tracks with the cuts.
