From what I understand about “ELO inflation”, it refers to the effect that the Top 100 FIDE players had 2600 ELO in 1970, but 2700 ELO today. It has been argued that simply the level increased, as more very good players entered the field. The ELO number as such should be fair in both eras (after playing infinitely many games...). I don’t think that it is an issue for computer chess comparisons. Let me know if you have other data/information!
