Out of round campagnolo Potenza chainring?

I lost a couple of fastening screws on my 34t ring, bought new screws, was about the replace them and discovered the ring holes do not align with the spider holes. Two match but the other two are off by a couple mm. The ring isn't bent, it still lays flush against the spider, but is it possible that by pedaling without all 4 screws, I managed to warp the ring out of round? It seems impossible a human could generate that much force.
