I am glad you are regularly using the builtin Eclipse formatter, BUT you also have to user your JUDGEMENT sometimes!   This expression if very hard to read.  You should obviously manually format it as:

return ClientPluginUtils.isPluginVisible() ? 
       ((160f - p.x) * ((p.x > 175) ? 0.81f : 0.7f) / 160f) : 
       ((160f - p.x) * ((p.x > 175) ? 0.7f : 0.73f) / 160f);

Of course, this means you can't just reformat the whole file again, but that's life!  You can still reformat individual methods as needed.
