The block was found 20 seconds. After the previous block.
Since 10 minutes is normal time 600 to 20 = 30 to 1
30 x 43kb = about 1.3 mb
Since 1 mb is top size and 1/30 of it is 33.3kb.
So a 20 second block should be 33.3kb.
So Kano had a large block with 43 kb once time is factored in
Of course, and if any block will be found in 5 min after the previous one, it would be at .65 MB? It can't be true.
