The thing is he's one of the most economical bowlers in the world, and ATM there's no way to differentiate between a rating for averages and E/Rs.
E.g. in one of my county games I brought Vettori as my overseas player, yes his average was realistic in the low-mid 30's, but he was going at over 5s in 40 over, and over 10s in 20 over.
In ODI cricket over the last four years, he always averaged below 29 and below 4.3 runs an over.
Well, the fact that he's been rated as high as he has been in the original database tells us that the bowling rating that we've found so far just controls the wickets/average of the bowler & not the economy rate so if you rate him too well hoping that his RPO will decrease then that's not going to happen & IF there's an RPO rating then we'll just have to wait till someone finds it; moreover, there's one major factor that affects how the statistics will pan out i.e. US/GAMERS, so for example, if I bat Ponting on full aggression with his regular rating then I don't think he'll even average 20 so it's possible that players may not perform according to expectations even if the ratings are accurate so how WE use players can influence their statistics somewhat as well, just to put it in context, I played 3 SLA in T20s & all of their season-RPOs were around 6 or below & all of their bowling ratings are over 1000+
It's also very hard when you're trying to rate one player across all three forms of the game with one rating.
I agree it's annoying to rate players across formats (& I'd say across levels of Cricket as well like some are God at FC but average or pathetic at International level, etc) so it becomes difficult to rate people like Sehwag, Jayawardene who're average in ODIs but God in Tests or someone like Dhoni (or someone like Michael Bevan in the past) who's good in Tests but God in ODIs. I hope that there're format-specific ratings as well as level-specific ratings & hopefully, we'll be able to find them out to make the game more exciting & realistic.
Well personally I believe that there is a modifier that determines economy rate and performance in different formats of the game.
I agree about RPOs as I've noticed that even with IDENTICAL fields & bowling strategy, people like Flintoff & Chapple always seem to go at less than 3 RPO, sometimes less than 2 RPO while Sajid Mahmood always goes for over 3 RPO, sometimes higher so it seems that there's likely a RPO-specific rating as well, it won't be easy to find it out but I read in the other thread that you were trying to find it, have you as yet met with even a semblance of a break-through?
The thing with Vettori is that he is probably the second/third best spinner in the world at the moment. Top would be Murali, but then after him is people like Swann, Vettori, Shakib and Hauritz. They all have averages in the low 30s. Does that mean they should all have reasonable bad ratings?
Well, I don't know what you might consider as a bad rating but I'd say, in order for it to be realistic, they all need to be rated in such a manner that there's enough of a justifiable amount of difference between their rating & ratings of Murali & Steyn, if we consider those two as benchmarks of sorts so that the statistical realism within the game is kept in tact.
Vettori's rating is so bad because he's had really bad support bowlers. It's feasible that if he has some decent bowlers by his side (that might happen in ICC with regens), he'll improve his statistics. His average in tests when playing with Bond was 24 or something.
Firstly, talking of REAL LIFE, bowlers like Bond are very hard to find for most countries, especially NZ I suppose, due to the smaller pool of players, so in REAL LIFE, probabilities say that they're unlikely to find another Bond, forget about THREE/FOUR (talking of regen super-bowlers), at least till Vettori finishes his career, so in real life, in all likelihood he'll finish with an average of 33-34 or thereabouts so the question of how good the regens around him might be becomes inconsequential as it won't be the case in real life & hence rating him well just because he might get good regen-support is still unrealistic as it probably wouldn't mirror real life, PLUS, just to consider that scenario, if he does get good regen-support then his averages will automatically be much lower even with a relatively high, realistic rating as he'll likely end up with many more cheap tail-end wickets as well as not go for as many runs against the Top & Middle-order of oppositions as he might if there was no good regen-support so that should take care of itself, WITHOUT us/gamers having to give him unrealistic rating.
I know you're his fan & rating him low doesn't feel good, especially when one knows that he's MUCH BETTER than some who might end up being rated lower than him (especially among pacers since spinners will generally have to be rated worse than pacers) but if that's not done then all the realism is taken away & again, if one doesn't care much for realism & realistic statistics then it'd be alright to rate players on "value" as long as they're enojoying the game which is what counts but for ME personally, I like Vettori but if he averaged too much below his real-life average (or higher than his real-life average for that matter) then the game just wouldn't be as enjoyable but to each his own I guess but so far as rating realistically to produce real-life-like results is concerned, production of realistic statistics will have to be taken into account while editing for realism. Cheers.
