said by SSidlov:Uncapped means they mean that we have NO TOTAL BYTE LIMITATION on the amount of downloads or uploads; I'm not a big (IMHO) uploader but here's a chart from December....
OOPS. My comment was based on my confusing the use of the term "Capped" to mean Speed Limits with your use of it to mean Transfer Volume Limits. I apologize for this confusion. Using the phrase "Speed Capping" or "Transfer Volume Capping" [or similar phrases] can help explain which type of limiting is being discussed (in the absence other text that explains the context).
