Not enough close game.
Out of 45 games, I can only remember two close game - Pak vs SA and Afg vs Australia.
sadly yes, toss hasn't been that influential, England won 7 and went out, and pretty even on bat 1st vs bat 2nd
Most tosses won
7 England
5 New Zealand*, Holland, Bangladesh
4 Sri Lanka, Australia, India**, Pakistan
2 South Africa
*kiwis elected to bowl every time
**didn't seem to matter if they batted or bowled, but India got the best preparation in chasing successfully first five games, and defending last four
Totals (batting 1st)
400 or more : P3 W2 L1 (Won 66.67%)
350-399 : P8 W8 L0 (Won 100.00%
300-349 : P7 W5 L2 (Won 71.43%)
250-299 : P13 W4 L9 (Won 30.77%)
200-249 : P8 W3 L5 (Won 37.50%)
149-199 : P6 W0 L6 (Won 0.00%)
lowest total to win batting 1st was 229 all out by Holland vs Bangladesh, before the deshis worked some dirty tricks into their game. India also scored 229/9 vs England, producing the bigger margin.
Bat 1st vs Bat 2nd
Bat 1st (elected to) : P20 W7 L13
Bat 1st (inserted) : P25 W15 L10
Bat 2nd (elected to) : P25 W10 L15
Bat 2nd (asked to) : P20 W13 L7
22-23 won batting 1st vs won chasing, won toss and won game just 17/45
Closest margins
5 runs : AUS 388 vs NZL 383/9
21 runs* : NZL 401/6 vs PAK 200/1
33 runs : AUS 286 vs ENG 253
38 runs : HOL 245/8 vs SAF 207
1 wicket : PAK 270 vs SAF 271/9
3 wickets : SRL 279 vs BAN 282/7 a timed out 'classic'
3 wickets : AFG 291/5 vs AUS 293/7 or should that be Maxwell?
*determined by worthless duck method, kiwis batted 50 overs, Pakistan's target/score off 25.3 overs, I apply the WTF approach as to how a target can be so low when you have around half the overs but ALL your wickets, as good a chase as Pakistan were putting on.
isn't just about the margin, how many of the games were a contest with 25% or less to go? (although some may counter that with the Maxwell factor, a one in a thousand or more longshot exception doesn't make the rule, as most sides capitulate in same situation)
biggest margins
7+ wickets : x11
6 wickets : x3
200+ runs : x4
100-199 runs : x9
50-99 runs : x6
so 19 of the 22 games won by the side batting first were by margins of 50+ and 13 of those by 100+, although why the Pakistan chase was measured by runs is anyone's guess
amusing stat - South Africa asked to bat 4 times
428/5 vs Sri Lanka- won by 102 runs
311/7 vs Australia - won by 134 runs
399/7 vs England - won by 229 runs
357/4 vs New Zealand - won by 190 runs
(3 over 350, you'd think after the 1st total of 300+ captains would get an inkling, after 2nd more so, 3rd for sure, 4th time just plain kiwi)
