This past draw was actually quite interesting when you look at the numbers...
The last time 19 showed up was draw 429, which was the 3rd time in a row.
The last time 11-19 came up was draw 428, which is also the last time we saw 47, and this draw also included 21.
37 and 40 have appeared recently together in draw 440, 433, 425.
But to me the most interesting is the 23-28 pair. They repeated in the same positions from two draws ago, but if you look back recently, you'll see that they've been paired together often. And if 23 shows up alone to the party, 28 shows up late in the next draw. Along with 23-28, 24 is not far behind (if not together). More than once, 24 has followed 28 after 28 followed 23 (see 440-439-438, 435-434-433, 431). Within 2-4 draws of 24 showing up, 23 arrives single or paired with 28.
