Do you actually know the process of producing renders? The majority of time goes into creating the scene (environment assets, lighting, whatever DAZ settings you use, setting up characters and their clothing). Once that's done, you mostly just pose characters and change camera angles for each render. Render times are in the single digit minutes with L&P's rigs.
So no, 4.25 renders is abysmal, especially considering your example only has renders inside an empty Sauna asset with women wrapped in towels and nothing else (see
Dr.SigmundFap's post above).
You also seem to not really be aware of the fact that L&P is getting slower and slower every single year. Good render quality does not mean you produce less overall renders every year either. You might be new to this project and so I can't blame you for trying to be positive about this, but you'll eventually come to the realization that with L&P it is ALWAYS a downhill ride, never up or even a constant.
And no, I'm not here "demanding" him to work faster or provide me with any particular content as yes, I'm not paying this guy anymore. Been there, done that. He can do whatever he wants, and I can come here and criticize his statements, straight up lies, slow development and the above mentioned constant downhill ride for years.
