It would be nice to have some official word on this. Nilxain did a lot of research on this and posted here:

Measurements give as +.50 and +.80 like Kendillin probably has are very likely increases in meters and not a percentage increase. That would be consistent with how other weapon measurements work. Full damage radius bonuses of x1.15 and x1.20 would be percentage increases.
Would prefer they just added it to the data card so we all know for certain what the value is. C'mon TRION!
