The Placeables are untranslatable elements, such as tags, graphics, numbers and fields. If you deduct the number of tags from the total of placeables then you will be left with the numbers.
I played with this a little and it seems to work on the simple examples I gave myself. If you have problems with this report back and we can take a better look.
In one job to a Japanese firm via one Chinese agency, we had dispute on work counts. I had been paid continuously by counting with MS Word that gave larger counts than Trados. The jobs were not translated with Trados. One day, the Chinese agency told that I would be paid for the last jobs by counting with Trados. This was not reasonable and I discontinued the newer assignments. I also use Trados to count words to recheck those of the agency. I found that word counts changed with Workbench setting on tags, placeables, options, tag DTD files etc. This has been a very good finding to me.
