BABN $50s, $100s wow.

Okay well this is a starting point:
AHF
9247xxx 99/99
9228xxx 99/99

This means that a sheet of 45 has to divide into 45 parts evenly, into an amount that is less than the difference of the said numbers above. So that one note gets layered onto the other one, since they are the same position.

Either that, or the notes are part of the same superbrick (that gets dissassembled- or run off at the 1000 point) Who knows? not me.

To contrast this is a pair of AHE notes that are:
3870xxx 75/79
3875xxx 75/79, meaning that the skip numbering should be at least 6000, since notes within 5000 + are the same position.
6000 x 45 = 270,000, which is greater than the 19 thousand difference in the above stated AHF notes.

So, the least skip numbering that $50s could be is ruled out because it is greater than the possibility based on the AHF notes listed above.

This implies logically that the skip numbering must include
9228xxx and
9247xxx in the same stack, before the skip to the next position's starting number.

The first number greater than 19 thousand is 20 thousand.
Can 45 be split into 20,000? not very nicely.
Can 45 be split into 22,500? yes,by skip numbering by 500 on a sheet of 45.

Sidenote: How on earth could BABN $100s all have the same FP/BP? ALL four notes below are 56/74.
BKJ 9236xxx
BKJ 9156xxx
BKL 7516xxx
BKL 6236xxx

Note that they are multiples of 40,000 apart. Again, this could only work if there was a 40 on sheet, which is what is understood to be at this time, not the case. BABN are supposedly using the 45/on sheets - we assume this because the range of the position numbers is from 55 to 99 (45 total).

9236-9156 = 80,000.
9156 - (80,000 * 20) = 7556xxx
BUT since we are targeting 7516xxx, we know that 80K for skips will not work, it is too large. However 40,000 will work.
9156 - (40,000*41) = 7516xxx. AHA!!

Again now,
7516xxx - (40,000*23) = 6236xxx.

Conclusion: Between all four of these above listed $100 notes, 40,000 does work as a skip. The fun part is the testing for truth.

Also to note, that it is possible for the skip to be very low, since I do have also to report:
BKL 4690xxx 83/71 and
BKL 4693xxx 93/98
Implying that a skip could happen anywhere from 3000 downwards.
BUT sicne if we skip by 2000 (or higher, then to map each note on top of eachother, there would be a contradiction, since they map only on the 40,000 * (some odd number) --> meaning that an even number would not cause the mapping to be successful (on on top of the other in the right position).

So, It cannot be 2000 or greater, but it has to be 3000 or lower, and 3000 doesn't map them on to begin with, whther you skip by 40 OR 45, so rule 3000 out completely, and you are left with a skip of 1000.

NOTE: This is based on new research. The hypothesis that is true will stand the test of fire.
So, My hypothesis for the BABN $100s is 1000 skip, and 40 on. Please no concrete solutions to be drawn from this yet. It needs to be tested alot. Not before the $5s are handled first though...

END OF NOTE on $100s...
*****************

Back to the $50s? These ones are crazy. This could take a while.
