the hard thing to do is practice bowling the so called right way
as it is boring
a foot ball team dose not practice a hole game they just practice a peace of the game. or certain plays.

a base ball team splits up its practice and hits balls and catches balls

so in bowling maybe we should do the same thing
a game of strike balls
a game of 10 pins spares
a game of 7 pins spares
and so on

this is a very hard thing to do as it is really boring
but it helps ive tried it
