TGV Lyria punctuality

Does anyone happen to have any stats on the punctuality of the TGV Lyria?

I’m thinking of booking a super cheap ticket, but this involves a rather tight connection (1hr10min – close for comfort with separate tickets) in Geneva. If I miss the connection I’ll be out many dollars indeed.

I’m inclined to go for it – 3hr25 from Paris, unlikely to be delayed by 1/3 of running time?
