Agfa G74C developer, how to?

Hello fellows,

I just bought from a photographer who switches to digital bunch of Agfa g74c developer. To be precise, 5l of each g74c A and B solutions.
Needless to say that this is the first time I've heard about this, but I want to give it a try.
He gave me initial instruction:
1 part A + 30 parts water + 1 part B to make working solution.
Dev time for Kodak Tri X is 7 mins 20C
For sure that I will try but also want to listen from experts here if anyone has worked with this developer before. Quickly read from user manual, I understand that this is mainly used to develop Aviphot Pan film rather than that of normal bw film as mentioned in it's data sheet:

This developer can also be used for other types of continuous tone applications, if necessary with a different dilution rate need to achieve longer development times.

Thank you for your time.

Not quite, it should be usable for any b&w film capable of withstanding 30° processing temperature.
Its main characteristic seems both to yield short development time and tweaking of the characteristic curve by changing the developing time.

To find the times for diluted baths I asssume you best do tests.

Well, I finally can do a test by myself.
Based on provided instruction, I modify a littlbe and do a test first with one roll Kentmere 100, with following recipe
*************
Agfa G74C part A: 30ml
Water: 960ml
Agfa G74C part B: 30ml
All to make 1020ml working solution
*************
I develope Kentmenre 100 within 7mins 20oC with above solution,
Checking the negative, I found that the highlight was a little bit blown out.

The 2nd try, I cut the time to 6 mins, the film was Kentmere 400
And the result is very satisfied.
I would say for the first impressions, Agfa G47C (1-32-1) creats quite similar results with Kodak HC-110 (1-31)
