Won "overall"? Well of course. It was the cheapest iso 100 film in the market. For the price it was the best "overall" film by far. And one of my all time favorite, partly because of its gorgeous looks and partly because it was the cheapest :)
RMS ratings place APX second to TMX in the granularity department and very, very far away in the sharpness/resolving department. You may not agree with this but it's all over Google and it's all over my prints as well. I can't argue against that.
PE, it's heartening to see a guy doing his work and liking it, after serving his term. I wish I had some of that. Because the day these printing presses are dragged out of here, there never was a man thinking good riddance more than I will be.. Although I still do good work, and don't get careless just because I'd rather be at the dentist at the time. I don't think I'd deserve the respect of your type if I hated it AND did careless work just to escape it quicker. I'm not sure any of that even computes.
If by claiming it was not fine grained you mean it was coarser grained than TMX, I agree. So is everything else in conventional film, even Pan-X was. But it was finer grained than Plus-X, for example. Since you like RMS figures, APX100 was rated at RMS 9, Plus-X at RMS 10:
You may not agree with that either but it's all over the web. ;)
