I note that the V fragment has a somewhat different orbit, especially
inclination, but also orbital period, than the rest.

The T and U fragment's inclination are also outliers.

What could cause so violent a separation, and could that be a mechanism
for deflecting comets ?

Or is the V fragment unrelated to 73P ?

I used Heavens Above for source, and I have written to Ron about it.
