Man, I had a similar experience working with code from a French manufacturer. The comments were mostly translatable, but the variable names were hell. It's bad enough trying to figure out in English whether acc is an abbreviation of acceleration, or accuracy, or some acronym, etc. Trying to expand a three letter abbreviations in a language you don't know it's nearly impossible.

Made me really lean towards never abbreviating in variable names unless it was extremely necessary for brevity, and also provide good comments.
