My theory is with a self bow, the B50 string stretches a lot more than the new high tech strings do, so instead of the limbs stopping abruptly with the high tech strings on the bow, the B50 string allows the limbs to travel a tad more and gives the arrow a longer power stroke so to speak.

Not sure how we got on selfbows, but Maiden Voyage was tillered flatbow style and Bear Nessesities was facet tiller style via Dean Torges.

Don't have a clue why b50 was faster but it was. And of course quieter, although either was quiet enough for hunting as selfbows are inherently the quietest bows anyway.

Also was called crazy for stating one particular arrow shaft allowing me to shoot 150 to 225 grain heads off of bows ranging from 58 to 78#s. But others soon found out the same validating I had 'defied physics'.

Just goes to show ya , we never stop learning....

  after many years of bow building I still get one now and then that just fights me all the way though for no good reason at all. No rhyme, nor reason detected , or ever figured out why..... "Some times you get da lion.... Sometimes da lion get you."
