Chuckles, I have never "lost sight" of the fact that others on this forum have knowledge in equal measure. In fact, I'm sure there are others who have quite a lot more knowledge than me in several areas. Film photography, and specifically film processing, just happens to be an area that I'm very well versed in, and so I'm answering according to that knowledge. No one is required to agree with me, however I will maintain that I have not treated you or anyone else with any disrespect.
That said, I will respectfully disagree with some of your statements in this most recent post.
Is not overdeveloping actually raising sensitivity of the film rating but just giving it a different title/name......? Push-processing is used for underexposure (accidental?) therefore the film sensitivity has been incorrectly rated.
First, a 10% increase in development is not necessarily overdeveloping. Manufacturer processing times are a guidelines only, and increased processing times (typically in the range of 10 - 25%) in order to achieve the desired negative density are part of the expected process. Equally, a slight decrease in development time will decrease apparent contrast. In fact, it's a cornerstone of the zone system.
Push processing is a perfectly legitimate and well-used method for handling low light and increasing film speed. It is not a typically accepted bail-out for accidental underexposure. Certainly some will use it as a bail-out (just as some people use photoshop as a bail-out) but that is certainly not all it is intended for.
What you're talking about here is effectively overexposing which will cause contrast issues, in this case what is required
No, I'm not talking about overexposure. Overexposure happens in the camera. Overdevelopment happens in the processing. I'm talking about neither, actually. I'm talking about a very slight increase in development to slightly increase apparent contrast.
I never called into question your advice at all, why should I if it is accurate? I just got the impression you never noticed I used the term 'finality'.
Actually, I didn't overlook your use of the term "finality." I merely pointed out that a 10% increase in development time is so far from "finality" as to make it a non-issue in this case.
Again, I'm sorry you feel disrespected. I intended nor implied any disrespect, but rather was simply aiming to give John the detailed information he needs to decide his initial course of action. Nobody is required to agree with me whatsoever.
