Agfa ortho 25

Agfa in their booklet "Dokumentenfotografie fuer Amateure" suggest:
Rodinal 1 + 200 + 1% waterless Soda (Sodium Carbonate sicc.).
[5 ml Rodinal. Fill to 1 Liter with 20C water. Add 10g Soda sicc. and use immediately]
The times for Agfa Ortho 25 given were 6 min @ 20C. "Agfa Inversion": 1 min. continuous followed by inversion every 30 seconds.

I just want to ask, since the my dev tanks are 500ml full, should I cut half the quantites, so 500/201=2.48ml of rodinal+5g of soda sicc? Or I do what you said, but use only 500ml of the solution?

Do as they say, the 5ml is the minimum Rodinal,they suggest per film, volume is less important.

Yes, but one can develop with 3ml of rodinal, never had a bad experience with less of 5ml, but in this case, I do not want to risk it. Thank you Ian!
