Certainly true jun23 that he posts screenshots in the records forum that are a waste of everyones time and should post his bugged screenshots in one post named something along the lines of "bugged records."
However if you look at the overs bowled, he averages something like 4 overs a game, and runs conceeded something like 5 a game. So I reckon considering he's played a lot of games, he has bowled this offie almost non-stop which would if he on average bowled 30 overs a match with him (which is roughly what he is bowling in the test matches) then he would have around 9000 overs bowled, plus his test match overs for FC figures which comes to already around, or even upwards of 11000 overs bowled.
Then for runs conceded it would be upwards of about 22500, plus the 2000 from test cricket for a total most likely in excess of 25000 runs conceded in FC cricket. This was based on a run per over rate of around 2.5 in FC cricket, somewhat mirroring his test rpo.
Now this is being pretty generous, that he has only conceded 25,000 runs in his career, but using that as a rough benchmark it gives him a bowling average of around 17, something that is a whole lot more believable
Doesn't make it a very honourable record however considering he would have known that a while ago it was a lot higher, and would have played on for 1000 runs worth of matches to at least make it.. in his eyes only.. believable.
Edit - If anyone ever reads this.. do ignore my theory as checking my own game, runs conceeded can go on for a very long time!
