Shows more info about Science Labs in the Editor and Flight (as PAW Group):

• Power Usage
• Science Storage
• Data to Science Convertion Ratio
• Research Speed Modificators
• Data Bonuses

Parts:

• MPL-LG-6: enhanced copy of the stock Lab with unlocked all 6 seats — 2 seats on each floor.
  Data-to-Science conversion is 1:6, but the Lab is 10 times slower than stock MPL-LG-2.
• MPL-DSD-2: 1.875m early progression Lab.
  Data-to-Science conversion is 1:2, but the Lab is 10 times quicker than stock MPL-LG-2.

Credits :

MPL-LG-6 originate in the 6 Crew Science Lab, but ScienceLabInfo does not replace the stock Lab and does change stats.
The model of MPL-DSD-2 is by JDCollie, and originates in the DSD Mobile Labs by Kielm. The texture has changed a bit, the part has been rescaled to 1.875m and has changed stats.

Note

"The Lab Modifier" in the GUI is 2 ModuleScienceConverter fields (dataProcessingMultiplier, researchTime) combined:

LabRateModifier = dataProcessingMultiplier / 0.5 × 10^(7 - researchTime)

so LabRateModifier is linear and equals 1.0 for the stock lab.
