PPU every 113.667 CPU (3 CPU = 1 PPU)

113.667	to 113 -> added 113   or to 114 -> added 114
227.333	to 227 -> added 114   or to 228 -> added 114
341.000  to 341 -> added 114  or to 341 -> added 113
454.667  to 454 -> added 113  or to 455 -> added 114
568.333 to 568. -> added 114  or to 569 -> added 114
682.000 to 682. -> added 114  or to 682 -> added 113
795.667 to 795  -> added 113  or to 796 -> added 114

So pattern is [113, 114, 114]
Alternate pattern using ceil is [114, 114, 113] -> this is probably better

CPU:
Next PPU at cycle 0+113 (pattern 0)
1 	1
1	  2
20	22
80	102
20	122
PPU update. FFWD next PPU at cycle 113+114=227 (pattern 1)
30	152
500	652
PPU update. FFWD next PPU at cycle 227+114=341 (pattern 2)
PPU update. FFWD next PPU at cycle 341+113=454 (pattern 0)
PPU update. FFWD next PPU at cycle 454+114=568 (pattern 1)
PPU update. FFWD next PPU at cycle 568+114=682 (pattern 2)
