The defintion of "pressure" for batsmen in a test match
As part of my ongoing Test batsmen ratings, I want to do a study on how many "pressure centuries" the best batsmen in Test history have scored.
Just want to get some ideas on how "pressure" is defined.
Here are my four criteria.
a) Scored in any team innings under 400
b) Scored in the 2nd innings of a match in a team innings over 400, when the team was chasing a first innings score of over 400
b) Scored in a team innings of over 400 but the team went on to lose the match (very rare)
c) Scored in the 3rd innings of a match, except for when a team's first innings lead is over 150, and except for when by that stage a result is out of the question (which would be my own interpretation)
d) Scored in any 4th innings of a match (in some 4th innings' one could argue that a result is out of the question, but I figure that if one batsmen has time to score a century, then the bowling team has time to bowl his side out.)
What do you think?
