As I said, it would be instructive.
Rain, and admittedly not the greatest of drainage systems (remember the era) often played a significant role in some of those draws.
@SillyCowCorner1 would attest that Bourda was always good for a missed day or two, in Barbados the running joke was that the best way to assure rain was to schedule a test match.
Not an excuse, obviously only impacted home games and doesn't cover what ever else ailed the team, but was a factor. Also for some reason, and contrary to popular belief, most of the WI pitches were not conducive to pace bowling. I'm also not saying it wasn't sporting or a bad thing for the record.
And again,
not making excuses, but it contributed...
