Just been looking at toss wins, electing to bat or bowl and outcomes. Also factored in whether you'd have expected the side that won to have won anyway
Chose to bat : P4 W0 L4
Chose to bowl : P13 W4 L9
Inserted : P13 W9 L4
Asked to chase : P4 W4 L0
As you might expect, paired, despite no success electing to bat 9 sides asked to bat won (out of 13) and is pretty even on wins, 9-8 to target setters
Out of 17 results to date I'd venture only FOUR have been heavy duty clashes, where you mightn't be sure of the winner (ENG vs NZL, AUS vs IND, SAF vs AUS, PAK vs IND) You could argue other clashes involving Sri Lanka and Bangladesh, but pretty much all games involving them have gone to form including deshi win over Afghanistan although could argue that was not necessarily destined to be easy.
of the four heavy duty clashes you had chose to bowl and won (twice), chose to bowl and lost, chose to bat and lost so whilst no successes chosing to bat there was a mix chosing to bowl
Both the upsets/shocks were where a big gun chose to bowl..... only big gun that chose to bat, and lost, was Australia vs India and maybe as much down to the opponent as the decision ie maybe opting to bat isn't a mistake, depends if you are playing India or some other big gun on their game
including last point I checked the current game :
average runs per wicket - bat 1st = 32.8, bat 2nd = 36.6
run rate - bat 1st = 5.84, bat 2nd =5.69
obviously includes minnows, bowled out cheaply etc but is only 6-8 to side batting 1st in terms of bowled out, 11-8 if you extend that to 9-10 wickets lost
somewhat surprisingly only one side, South Africa 428/5, has lost 5 wickets or less batting first
wickets lost
10 : bat 1st = 6, bat 2nd = 8
9 : bat 1st = 5, bat 2nd =0
8 : bat 1st = 3, bat 2nd =0
7 : bat 1st = 2, bat 2nd =0
6 : bat 1st = 1, bat 2nd =0
5 : bat 1st = 1, bat 2nd =1
1-4 : bat 1st = 0, bat 2nd = 8
I haven't including Pakistan, last time I look, 0 wickets down but have aussie total as the innings was completed. Quite remarkable in chasing that 8 sides were all out and 8 sides lost less than 5 wickets, would think there'd be a bit more of a spread/contest.
