2 Team NBA Teaser question?

2 Team NBA Teaser question? I have a local book who is now offering 2 team 6pt NBA teasers at -130. Isn't this much lower than what they should be charging? Isn't the 6th point on certain point buckets a lay up? For example 1pt to 6pt home and away dogs teased up...isn't that close to a 78% play (O/U less than 187)? Does anybody else have a database that can verify this for me?
Actually any input on 6pt teasers would be helpful?
