[Genome] Reg. Potential scores

[Garavito, Pilar]

Dear genome-ucsc,
In relation to Regulation Potential score,  is there a defined upper limit or it varies from gene to gene? The upper limit shown  in the graphic for the 7X Reg Pot is 0.1  but in the table list we see there are values greater that 0.1 and what does that mean?
Is there a way to filter different  "starts and ends" of RP data within a predefined  region since I obtained several gaps in the final output.
Thanks,
Pilar
