Yes, your file sizes are all okay! 200MB is actually 204,800kb. Files should work correctly if under 204,800 kb. Anything over that, and something or some things might not load. It's best NOT to go over. That is why I recommend saving your .ebc file as it gets close to 200MB. Then, if you go over, you can delete the .ebc file that went over and revert back to the saved one. If you keep track of everything that is installed in the .ebc files, you could reinstall them minus whatever file(s) pushed them over. Then install those extra items in any .ebc files that have extra room, making sure to back them up first.
Fortunately you stayed under the magic number! Congrats!
On compilation dups - if you followed my spreadsheet, you should have avoided any dups. Dups will not hurt anything my themselves. They may just make load time slower and add to general game bloat. Not having duplicates means that your file size will be just a little bit smaller,
