Wow, well done! I found [6,7,8] as well:

6,7,8

6,7,5,3

6,7,1,4,3

6,8,4,3

6,8,7

6,3,5,7

6,2,1,5,7

8,1,5,7

8,6,7

8,4,2,1,6

8,4,3,6

8,7,6

Yeah, the [n,n+1] is only a problem when there isn't enough wiggle room between the numbers. ex: [2,3] and [3,4]

[3,4]

--> [1,2,4] --> 4 can't split because 2/2 and 3/1 are invalid

--> 4 can't initially split because 2/2 and 3/1 are both invalid

[5,6] --> [5,4,2] --> [5,1,3,2] --> [6,3,2] --> [6,5]

[7,8] --> [7,3,5] --> [7,1,2,5] --> [8,2,5] --> [8,7]

When you add more numbers, you need more wiggle room. So, [4,5,6] is problematic and probably [5,6,7].

[4,5,6]

--> [3,1,5,6] --> 6 can't break into 3, nor 5/1. It can do 4/2, but then 5 can't split. 5 also can't split.

--> [4,2,3,6] --> [4,2,3,1,5] --> [6,4,5] --> 4 can't split into 2/2. It can split to 3/1 but then 5 can't split

--> 6 can't initially split at all because 3/3, 4/2, and 5/1 are invalid

Even if [6,7,8] has a solution, I'm sure [6,7,8,9] does not.

I think surfacing additional information would help increase confidence in the system when it raises a problem.

For example, keep a running passengerCount (or rather display it since it must(?) exist). If someone has a copied pass, their screen can show: Current Passenger Count 10 This Pass Last Scanned at 5

If the fraudster & legitimate passenger are back-to-back, that might add some confusion for the agent so they'd need a good way to display this. They can call out to the last person to come back to clear up confusion.

If the fraudster was much earlier, they'd have to go find them. Maybe take a picture of each passenger during pass-scan.

Or simpler: this would be simplified by using Steffen Method boarding [1]: you should know exactly which seat matches a given passenger count number.

I loved playing Psychopath back in 2006 and built a Java clone in 2007 for a class. I love how many awesome puzzles emerge as people pieced them together to make levels on top of the simple rules. I also remember enjoying Stick Avalanche & Boomshine. Thanks for all the fun times & awesome to bump into you!

I've started Pathology.

Lost there too doing the opposite... I tried to get ahead of 3 per minute by creating a nice stockpile. Dead from overfeeding.

Maybe I'm clashing with the specific phrasing since I haven't heard of a bias in the grading itself (i.e. a bias of the teacher), but rather a bias of the system. Schooling as a whole aligns more with girls' strengths as they're more consistent in the day-to-day (ex: organization, planning, homework) whereas boys tend to test better [0]. The weighting of assignments in a particular class could tip the benefit in either direction.

I could believe girls 'get graded higher' on written assignments due to generally better handwriting. I had poor handwriting (though recall at least one girl classmate with worse) and certainly received no credit on some correct answers as a result. I imagine a frustrated teacher reading through a chicken-scratch essay might dock some points - whether directly with a note calling it out (also happened to me), discreetly, or subconsciously.
