I asked the same question for the same reasons over year ago from this forum and from SkyGolf and the answer was and still is no . There is no boost option in JNPG's simulation and there isn't boost in ST.
And if you for example tweak SkyTraks altitude settings, it has no effect on JNPG. I also hoped I could use yards in SkyTrak and meters in JNPG, so it would give me that 10%. But the integration between them isn't that stupid:).
Then I realized I could change the altitude of the JNPG courses and did some googling. I can't remember exactly, but there is a particular altitude (over 1000 meters or so) where the ball flies 10% further than when played at the sea level. So I did some more research and found out that the altitude of JNPG courses was mentioned in those files that come with the courses. Unfortunately, I also find out later that JNPG courses don't read the altitude from those files, so changing them won't help.
There I was. Nothing could be done with my almost golf ball simulation to make it work more realisticly. I also knew that the LA was incorrect with almost golf balls (the LA is more shallow) and the feeling over all isn't the same. The dream of a real simulation started to tease me.
So I did some more research. I found a good golf net that was big enough and figured out how I would fasten it to the roof so it would protect the rest of the house. Then I found a cheap and tough enough impact screen to put in front of the net. Purchased a better hitting mat also and there it was, almost real golf simulation. Only one thing remains, the projector. It's the next fall's investment. Untill then, I'm using my 60 inch LG TV.
WARNING: No matter how good products you'll buy, nets will wear out and impact screens will wear out (mostly because of the ball spinn), so NEVER EVER use only one single net or screen to protect your loved ones, yourself or your home. Impact screen with the net is a fine combination. They protect each other and if the first one breaks down the other one catches the ball. Other possibility is to buy a large enough net so you can double back it.
