De modo que en esta carta me limito a hablarte de lo más concreto.

Question

How to understand "lo más concreto", most specific impressions or more specific impressions? Thanks.

Answer 1

You seem to be extrapolating meaning or reference to previous dialog which we don't have. We have nothing to relate lo concreto with impressions. The only meaning we can give lo conreto without any context is "real, actual, literal, factual, basic, simple,not abstract, specific, determined) Could you give us the previous sentence or two to see how it relates to impressions?

Answer 2

The context: Las impresiones que me han causado los primeros contactos son muy complejas y todavía no puedo formular ninguna apreciación clara y precisa de todo lo que he podido conocer. I wonder whether "lo más concreto" is grado superlativo relativo, or is it grado comparativo? Thanks a lot.
