Does fourth inning performance holds any criteria to measure a Batsman's performance?

I am talking about Fourth inning then then it will
be obviously Test cricket.I am not talking about
T20 test match because this type of matches have
not been played still.If T20 test match will come
in existence I don't know what they will call the
traditional Test Cricket.Anyone who don't like traditional
cricket might say it is Cricket of Senior Citizens.

Coming back to the point of fourth inning performance.
Many great said cricketers have performed bad in Fourth
inning but some have performed well.Many cricketer's
fourth inning score have bring win for their team but
many have record of not winning matches in which they
have performed well in fourth inning.

It's very hard to score runs in fourth inning
because does not remains as it was in start,batsman
have to play in pressure and also batsman feels tired
in the fourth inning.Sachin Tendulkar is great cricketer,
everybody knows but he have conflicted to make big score
in fourth inning.

Brian Lara played his cricket when West Indies Cricket
had lost his Crown of World Winners;there was nothing left
for West Indies.If a great cricketer is playing for a team
which seems to be nothing without him,does not guarantee
that team will have good record finally.This thing can be
taken as like If you will make Clive Lloyd as captain of
Bangladesh their record will not be improved anymore.
Brian Lara have made 860 runs in that fourth inning
of the Test which they lost finally.Brian Lara have played
well in Fourth inning but it have not improved overall
record of West Indies.Currently Brian Lara's work is being
done by Shivnarayan Chanderpaul.Chanderpaul is also
making runs in fourth inning but it get counted as
contribution in their lost.

Making runs in fourth inning is hard you will get to know
this by knowing that anyone have not yet scored total
2000 runs in fourth inning of Test.Talking about currently
playing and have total of more than 10000;Rahul Dravid
have scored 1320 runs in fourth inning.Brian Lara have
scored 1440 runs in fourth inning but have retired.
There are nearly 16 batman who have scored more than
1000 runs in fourth inning but none have scored 1000
runs that contributed in the team win.South Africa
skipper Greame Smith is very much closer to this record.
The tests in which SA batted in fourth inning and have
won out of this 16 in which Smith played he scored 919
runs with the average of 83.33 and total 3 centuries.
There are maximum 4 centuries have been scored by Sunil
Gavaskar and Ricky Ponting in fourth inning.The most
remarkable point about Smith's 3 century is they brought
win for the team.Ricky Ponting's 3 centuries out of 4
have brought win for the team.Sachin Tendulkar have
not scored at least 500 runs in fourth inning which have
bought win for the team.
