I should mention, incidentally, that the Suggest and the Instant suggestions are not the same... they can't be since there are only 5 Instant suggestions vs 10 Suggest suggestions... but they seem to be picked in the same order from the same list.
PS - Since I posted the above, Instant has reverted back to 10 Suggestions. They seem to be trying it both ways. Anyone else seeing this?
PPS - Very soon after posting, I left google.com and came back, and Instant, at least in the west coast US, is now back to 5 Suggestions. I'm also seeing European engines now offering Instant by default whether you're signed in or not... and on these it's 10 suggestions. I assume it will keep on changing for a while.
