Have you got the new Tour+ mode? Its very similar (probably identical) power curve to the 'Magic Tour" mode below. I find it natural but also has full power on tap when you pedal hard.

Apparently it has the latest firmware...
I still don't consider it that natural though, I get that it works in relation to your own effort but it still seems to over assist to me, maybe it's just the extra power over the E8000 I'm not used to...
Riding it back to back with my mates Brose 1.3 which has similar power it's still far keener, we both agreed on that.
