Question about Reflecta ProScan 10T

I am currently scanning negatives and have measured the following (resolution 3000ppi, 8 bit colour depth):
Scan duration (without prescan) incl. storage:
2'25" at 4170x2809 pixels = 11.7 MP
2'26" at 4191x2824 pixels = 11.8 MP
2'25" at 4151x2824 Pixel = 11.7 MP
I use Silverfast SE Plus as software and am extremely satisfied with it. Generally very happy with the ProScan 10T, previously had the Nikon Coolscan 4000ED until it went out of production (second-hand model).

With the Reflecta Pro Scan 10T I use the Silverfast AI Studio 8 software. I usually scan with the Workflow Pilot with the largest size and so I get 35mm colour negative scans in just under 3 minutes including saving (without preview).

at 2500 dpi and 8 bit colour depth 3 min

Preview scan approx. 1 minute
Final scan 2.5 - 3 minutes
