This song has a wicked broken jumpstream section, along with a 32nd note jumpstream section, which at least pushes it over the 50 mark, and it has horrid level rank stats.

A greater % of people have AAA'd and FC'd immigraniada than this 51. Let's look at a 53 released only a week earlier than immigraniada.

Tutti Frutti Summer Love - 53

The AAA count is slightly lower, but the FC % is slightly higher. The sloping off of the scores on the lower part of the scoreboard is similar to that of immigraniada. Let's look at one more, a 49.

With only a few hundred more players, it has about double the AAA count.

Here are two more songs of similar difficulty, but earlier release dates. The ratios though are still similar to immigraniada.

Immigraniada has a section of broken jumpstream, along with a 32nd note jumpstream section, unlike any under 50 difficulty song. I would make the argument, that based on the stats of songs with similar release dates and the patterns contained within the file, that immigraniada is a 52.
