If I had to shift 570 times on a single ride, I'd move elsewhere to find better riding.
How big is the Di2 battery physically? & how much does it weigh?
No need to be super defensive to your purchasing choice.
No need to act like you are the brand ambassador for the product.
My info mentioned is quoting XSHIFTER themself from your provided link. If what they said is not accurate then what can i trust? If only they just say it's ten thousands of shift, rather than just thousands...
Opposite of your preference, where i live is too flat. It actually take 1.5 hours drive to get to place where i can start the enjoyable ride with lots of rolling hill. When i use mech shifters i easily shift 3 time less than i do now. It's just so much easier to keep cadence and power near constant and change gear to suite the terrain on electronic gears. Also, it count 1 cog change as one shift.
Roll to top of the hill, from very easy gear to gear for fast descending, that's easily 7 shifts or more. 570 shifts doesn't sound excessive. Di2 battery shape like a long highlight pen that easily fit in seatpost. It weight 59g. Battery last longer when most of the communication is on wire. Wireless unit on di2 can have low polling rate just enough to tell bike computer after the shift already happen. It can delay for a second or so without effecting performance. Unlike high polling rate instant react wireless communication for shifting.
