You sir are very committed. Please keep us posted. For sure if there is anyone else at the event that has gearing info I would defer to that. If it happens for be for a different engine you can probably use the sheet I shared to extrapolate a similar gearing.
I’m still not 100% sure what engine you have, but here is the full list of sheets. If your model is not listed let me know and I’ll create a new one with the ratios from the homolgation sheet.
