I shoot ADOX 100 at about 100 box speed. Meaning that I have the meter set to that, do incident readings, and then look and see if I need to open up a bit? The film doesn't handle overexposure very well. But it isn't super sensitive; from your shots it looks like you have a good handle on exposing for the shadows.
The developer is HC-110. Diluted 1:100 (US stock from the bottle directly; child's medicine syringe used to measure- 4.5 ml/450ml water). 68F/20C. 8 minutes total. Agitate for the first minute, then six inversions every minute.
I go for somewhat thin negatives. i scan with an Epson v500, which doesn't have the greatest range. So 'full' negatives blow out on one end of the other. I've scanned these same negatives on an Imacon and I am certainly not using the full tonal range of that scanner. But I own a V500, not an Imacon- horses for courses.
I mention just to point out the little adjustments that can be involved with film. How the negatives will be printed or scanned is an integral of the whole process.
And yes, 1:100 is not really an official dilution. Oh well!
