IgorC: 190 vs 195 is oranges vs elephants ... seriously? Or did you read hundredandninetysomething vs twohundredandsixtysomething?

If it only takes a few sample signals to find one where 3.100 -V2 is ABXably better than 3.99 -V2 at the cost of 2.6 percent increase, then isn't that at this level a (small and preliminary) indication of a pretty good job? After all, the V of VBR is about knowing where to spend more bits.

1.
It's not about a few kbps for some samples. It's for ALL samples.

2.Who guarantee that quality improvement come from smarter algorithms and not from pure bitrate increase?

A 5 kbps difference really doesn't change quality because of this small increase in bitrate. Please do think of bitrate difference in terms of average bitrate difference for a representable set of full length regular tracks. If bitrate is significantly higher with problem sample snippets this is very welcome! And look at 3.98.4's average bitrate in my post above.
Your ABX log was about a rather modest improvement in quality. Maybe 5 kbps difference is sufficient to make up for this quality increase.
With the samples I tested there is a severe quality improvement however, and cannot be contributed to a 5 kbps higher average bitrate. But we do know that robert significantly improved on the machinery, the small increase in average bitrate is just a side effect of this.
