My previous set of RXS cleats was mounted about 4mm behind what Mavic has marked as the "0" mid-line of the shoe. This left the cleats say... 75% slid back on the track of the cleats. Cleat centerline = Mavic centerline -4mm. (Or Cleat centerline 4mm behind marked shoe centerline)

On Bonts: Using identical Time RXS cleats on the Bonts - sliding the cleat 100% of the way forward leaves them at Bont Grid Centerline +12mm.

Thus, the cleat holes are
Mavic: "Centermark" - 4mm = Existing Cleat Position.
Bont: "Mavic Centerline" -20mm for Bont Grid position + 12mm (max forward cleat position) +4mm (adjustment for cleat position on Mavics) = -4mm cleat position compared to Mavics, closest possible position to existing position.

Google tells me that Mavic's shoes are drilled waaaay far forward, and it would seem that yes, this is borne out by the fact that I can't get my cleats to line up, even sliding them all the way forward.

Am I thinking this out incorrectly? Is there something I could do differently?

Please help.
Thanks!

I didn't find the right solution from the Internet.
