The Elo system didn't exist until 100 years after Labourdonnais. There are several attempts to extend it backwards, but they're not well defined. It doesn't make sense to say Labourdonnais went "from 2600 to 2650" without changing his playing strength: it's an artifact of some particular guy's methodology to estimate historical ratings.
