India chased 280 against a significantly weaker Zim team and SA hammered a hapless WI side at the SCG.
I think when you have 2 equally matched sides, SA and NZ, the par totals are more applicable and more likely and are generally a better reference, while records are not!!
Obviously it's how the teams perform on the day but setting a target a team must have realistic goals in mind. You don't walk out at Eden Park and pace your innings with a total of 350 in mind when the highest total ever scored there is 340?!!!
With that in mind, 270 is a winning total batting first so if we 40/0 after 15 we on course!! If we 140/3 after 30, we on course!! If we 200/4 at the start of the batting power play, we on course!!
