Well, let's think about it.  Assuming no rain interruptions (oh no- I'm
starting to sound like an economist :-), Batsmen A has a runs/test "score"
of of 70.  Batsmen B has 60.  Little difference here.

Now, to bat 20 times in 10 tests, it is likely that your team is losing
a lot of the time.  It is also likely that A was a higher order batsman
(i.e. top three), and runs scored at the top of the order are *generally*
more valuable than those scored down the order.  I usually bat about 5 or 6,
so don't flame me over this statement!!  So it may well be than A has
performed very well in a losing side.

B on the other hand is obviously playing in a very strong team, where
lots of people are scoring runs.

I think an argument could be mounted to state that A is making a
more valuable contribution (which I think is the BEST indicator- though
hard to measure of course).  

Your example is an extreme one, and also leaves aside the "not-outs" factor.
I'll try to dig up some statistics on real players to see how my
argument holds up.

Any other thoughts?  

To be continued.

Guess who tries to measure it? C & L!

So who is the most VALUABLE batsman for Australia?

:-)

   Before I  go  any further,  let  me make  something clear...I'm not
   insisting  that rpi is the  best  method. Only that, runs-per-test,
   IMO, is not likely to be a better indicator than runs-per-innings.

   OK, when  I am  assuming  no not outs  here.   So  Batsman A has  a
   runs/test of 70 and rpi  of 35.  OTOH, batsman B  has rpt of 60 and
   rpi of 50.

   Sounds plausible enough.

   Likely enough.

   Aha...how would we know that B is not  a upper-order batman :-) All
   we know  that he batted 20  times  in 10 matches.  Suppose  a lower
   order batman gets to bat 20 times in 10 matches, this means that by
   default all the upper-order  batsmen  (in the situation   described
   above) have batted as well.  So we really can't deduce as to what's
   B's  number in the batting order.   If any thing, having scored 600
   runs in 12 innings indicates that B *is* an upper-order batsman.

   I take you mean strong "batting" team.  This is IMO by no means
   conclusive. (cf. Inzimam-ul-Haq, Martin Crowe)

   Like I said  in my previous post neither  method is perfect, but at
   least rpi takes into account how many times a batsman actually went
   out to bat, which is not the case in runs per test.

   The "not-out" factor is the real  ***, actually :-) I guess, the
   idea behind  using only  the  completed innings  in computing one's
   batting average was that  the batsman could  have scored more runs,
   but had to  stop for whatever  reason.  I  am  of the opinion  that
   these things even out in the long run...especially when it comes to
   comparing  two  players (since it   both cases  the  same rule will
   apply).

   As an afterthought  actually it really  doesn't  matter whether the
   "not-out" innings are  counted or not,   since the same measure  is
   being applied to all players --- of course the method is imperfect,
   I never denied that, did I :-)

]> Any other thoughts?  

   Perhaps we  can use "runs  per test"  (with the  qualification that
   only the Tests in which a batsman got to bat are  counted -- on the
   same lines as "runs per completed innings").  But if you really ask
   me, it's not likely to have much difference.  I did a little research
   on some data retrieved from CricInfo.  An edited version follows:

Some facts...when looking  at the column  under Avregae  (i.e. rpi) we
see Bradman is no. 1 followed by Greg Chappell and Alan Border.

Whereas when  the batsmen are ranked  according to  Runs per Test, the
list looks like this: Bradman, Mark Taylor, Bobby Simpson, Lawry, ...

I make no judgements here.  What do you think?  Does, IYO, your theory
is justified in  the  light of the  above data?   It's  an interesting
debate, let it continue :-)

  Sure...it's rare on rsc to have a purely cricket related discussion
  WITHOUT any flames :-)

                                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

That does it! Case closed. Any statistic which even suggests that Taylor,
Simpson and Lawry are better than Greg Chappell is a dud. And why are
they rated better by Runs/Test? For the simple reason that they are
openers and are therefore going to bat more often than a number 4 or 5
like Chappell. Runs per Test is obviously unfair.

Thanks for the great stats Syed....
