Rebuy strategy: do you ever stop rebuying?

[DMACM]

I did a 2+0 speed rebuy on party today. After the rebuy period ended 75% of the field was gone. I only survived this far because I rebought 28 times. Is it correct to go all in many times trying to double up in multiway pots? Would you ever give up and stop rebuying? I calculated that of the remaining players after the rebuy period their average investment was 48. Mine was 56 and my stack was lower than the average. I have looked for rebuy strategys on this forum does any one have a link to a good one?
