Yes, I have.
I've got best results with EI 80/20. I've used calibrated exposure meters.
I have also shot Provia 100F and E100 side by side: Same conditions, same camera and lens. Provia 100F is perfect at box speed of ISO 100/21.
E100 is best at EI 80/20.
The contrast curve of E100 is also a bit steeper than Provia 100F (resulting in a bit higher dynamic range Provia has).
