Hello!
Just came back from my CN exercise.
2020-05-03, HoE≈3meters (not so sure but definitely more than 2,5meters), Tair=8°C, Pair=757mmHg.
Watch correction = -0h01m02,5s (i.e. WT is "fast"), Index Correction = -0°00,1' (an "off-scale" I guess). "V" - Venus, "S" - Sun.
The "raw" data, no corrections applied:

I took them in alternating pairs to make the direct fix calculation more easy.
I hope the actual weather conditions were not too far from "normal" - i.e. correctable by official Refraction tables.
During the session I could not find Venus by naked eye, it was visible only through a Keplerian 7x scope with the correct altitude preset.
Warm regards and the best health wishes,
Tony
