In my first post of this thread i mentioned this article:

Sure, without a refection densitometer it is hard to tell exactly which grade one actually gets. But as far as i understood it, counting the number of clearly distinguishable steps between max black and paper white will at least tell me the grade within a reasonable amount of accuracy.

Using no filtration, I counted 9-10 steps, which according to the article corresponds to 1.35-1.50 log ER or roughly grade 0.5 (1.40 log ER).

And prints do indeed look too soft, but getting real black is of course just a question of exposure time with any negative and grade, when we ignore highlight exposure.
