For a 4:26-long track, I needed at least 133 seconds of overt source usage for the source material to be dominant in the arrangement. I didn't agree with Markus's timestamps exactly and thought some of the credit to flourishes was too generous (and that some of his timestamping was off), but it wasn't a big deal:
:00-:46.75, 1:30.75-2:13.25, 2:14.75-2:28, 2:48.5-2:55, 2:57.75-3:00.25, 3:09.5-3:33.75, 4:12.5-4:15 = 138.5 seconds or 52.06%
I counted the bassline from 2:07-2:28, which had already been in play earlier behind the Muda melody and was taken from Muda and adapted for the time signature, but held the same basic rhythm. When I stopwatch, I just need some direct and overt connection to the source tune in play, and the bassline there was a close enough match for me, where I recognized the adaptation of it. Close shave, but count it.
Arrangement-wise, I can understand the complaint of the sections not weaving together 100% smoothly, but I didn't have any problem with these transitions. Smooth work overall, and IMO an effective combination of two classic Mario Land themes that comfortably connected with the original writing.
