Lame 3.99.5: "%%%%%" instead of "*****" in VBR "bar graph"

Sometimes, when LAME converts .WAV tracks to MP3 via VBR, the "bar graph" in the verbose output will show some "%%%%%%" symbols.

So, instead of this:

CODE
    Frame          |  CPU time/estim | REAL time/estim | play/CPU |    ETA
  4000/4046   (99%)|    0:11/    0:11|    0:11/    0:11|   8.6168x|    0:00
32 [   0]
40 [   1] *
48 [   0]
56 [   5] *
64 [  10] *
80 [  19] *
96 [  50] **
112 [ 427] *************
128 [ 741] **********************
160 [2331] ********************************************************************
192 [ 397] ************
224 [  19] *
256 [   0]
320 [   0]
-------------------------------------------------------------------------------
   kbps        MS  %     long switch short %
  150.8      100.0        96.9   1.8   1.4


...it will show this:

CODE
    Frame          |  CPU time/estim | REAL time/estim | play/CPU |    ETA
  4000/4046   (99%)|    0:11/    0:11|    0:11/    0:11|   8.6168x|    0:00
32 [   0]
40 [   1] *
48 [   0]
56 [   5] *
64 [  10] *
80 [  19] *
96 [  50] **
112 [ 427] %%%%*********
128 [ 741] %%%%%%%***************
160 [2331] ********************************************************************
192 [ 397] ************
224 [  19] *
256 [   0]
320 [   0]
-------------------------------------------------------------------------------
   kbps        MS  %     long switch short %
  150.8      100.0        96.9   1.8   1.4


I have been trying to search to find out what this means, but I guess I can't figure out what to search for, as most web and forum search engines don't like "%%%%%". tongue.gif

Can anyone explain what this means?

using "lame asterisk percent" in the Google Custom Search box up top

{edit}
Also, you will see LR (Left/Right) and MS (Mid/Side) frames as percentages at the bottom of the histogram.

The strange thing is, it looks like J.Fleming is using -m f, since the bottom of his histograms says MS 100% and has no mention of LR, yet the second histogram shows % symbols for 112 and 128 kbps frames while still saying MS 100% at the bottom.

I think that's because J.Fleming manually created the second code by editing the first. Am I right?

I'm also assuming the second example was a manual edit. But the first one, if unedited, could have been forced joint stereo -or- it could simply mean the input was essentially mono (L = R).
