Comment (by markspieth):

 After being prompted by helen, Ive produced a timely update to my patchset
 which incorporates helens findings and some others that I noticed while
 testing.
 Use all patches prefixed 20141111- in that order.

 My results are as follows:
 ||Name||Program||Type||Actual||ng all hires||ng all new||Orig all||Helen
 all||
 ||The Loop||1011 20141031220000||SD||12||12||13||6||10||

 ||Downton Abbey||1007 20140427110000||SD||11||9||9||5||3||

 The previously mentioned settings are still relevant.
  * method is 1055 or ng_all for '''ng all new''' column
  * Actual is a guess from the R plot but is at most 1 out.
    {{{
    R
    > sc = read.table("loms1.csv",sep=",", header=TRUE)
    > plot(sc$Frame/25/60,sc$max)
    }}}

  * '''Orig all''' is without any patches
  * '''Helen all''' is with helens patches and method 31 or all
  * '''ng all hires''' is my previous algo before helen's inspired updates

 The updates are:
  * use original logo detector with helens mods
  * other helens mods for pillar box
  * updated to use helens bytesperline patch instead of the one I was using
 previously.
  * fix to coalesce segment scores which wasn't being done before helps
 with short program segments.
  * new log detector which is incomplete can be accessed with method
 '''ng_allx''' or 1055+256
  * use correct fps as players is just a wrong default. Only affects log
 output.

 I like the results Im getting and will put this into my main backend
 shortly.
 Not perfect by better than I am currently getting. I tried to pick a
 varied set of material.
 Thanks to helen for her work that prompted me to revisit something I'd
 been using for ages.

 As always feedback appreciated and YMMV.
 Note: view table in browser, mail won't do it justice.
