Hi Tanel, I have no idea but if you currently have 9 entries in a leaf block and the 10th entry you're about insert causes this type of split, then 9 entries (the 90% currently in the existing leaf node) remain and the new entry (10%) goes into the new leaf node.
A 90-10 (%) split. Possible with small blocks (say 2K) and large index entries (200ish bytes) when 2K blocks ruled the Oracle seas. Like I said I have no real idea but it's my theory and makes a good bed-time story.
