HC-110 Development Time

[Eddy Lin]

Hello guys.
I just know the HC-110 development time is linearity.
Is my data correct?

[TABLE=collapse]

Dilution
Time


A 1:15



B 1:31
1x


C 1:19



D 1:39
1.25x


E 1:47
1.5x


F 1:79
2.5x


G 1:119



H 1:63
2x

[/TABLE]

Are you multiplying the times all in reference to dilution A? I'm at a loss as to why you are doing this. It does not seem like a very practical way to figure out development times for HC-110. It's a well known, well used developer, and there are plenty of sources. Here's another: https://ludwig-hagelstein.de/the-unofficial-hc-110-helper/

This is the way it has always been done.

Of course, you would then fine-tune to fit your thermometer, metering, style and water...
