MLB Runline Odds

Can someone give me an approximate value of the +1.5 RL on a big dog in the MLB versus the ML.

For example, if the dog is +200 ML, can anyone give me what the average value would be on the +1.5 RL? I'm trying to do some testing and don't have the +1.5 RL available.

Just looking for an estimate or previous examples from last year.

Thanks!

I once talked to a bookmaker in Las Vegas and he told me on average every half point should have a value of 50 basispoints, meaning +1,5 in your example would result in -150...but as with everything, it depends...with such high odds you would probably be more in the area of -120 to -130 I guess...
