Narrative:
Flight atl rsw while circumnaving thunderstorms on jet route from atl to johnn (169 degree right of atl), requested from center permission to deviate to avoid 'build ups' center cleared deviation to west. After deviation, returned to jet route at which time center controller reported a 'system deviation', ostensibly with another aircraft in the area. At occurrence, aircraft was climbing to FL310, in and out of clouds, and receiving moderate to severe turbulence. (Flight was a heavy transport) no other aircraft were visible in the area. Center reported that crew may see same 'paper work' on the deviation. Controller was extremely busy with 3 - 4 other aircraft in the area.

Title: LESS THAN STANDARD SEPARATION BETWEEN CLIMBING DEVIATING ACR HVT AND OTHER IFR TFC.
Narrative: FLT ATL RSW WHILE CIRCUMNAVING THUNDERSTORMS ON JET ROUTE FROM ATL TO JOHNN (169 DEG R OF ATL), REQUESTED FROM CENTER PERMISSION TO DEVIATE TO AVOID 'BUILD UPS' CENTER CLRED DEVIATION TO WEST. AFTER DEVIATION, RETURNED TO JET ROUTE AT WHICH TIME CENTER CTLR REPORTED A 'SYSTEM DEVIATION', OSTENSIBLY WITH ANOTHER ACFT IN THE AREA. AT OCCURRENCE, ACFT WAS CLBING TO FL310, IN AND OUT OF CLOUDS, AND RECEIVING MODERATE TO SEVERE TURBULENCE. (FLIGHT WAS A HVT) NO OTHER ACFT WERE VISIBLE IN THE AREA. CENTER REPORTED THAT CREW MAY SEE SAME 'PAPER WORK' ON THE DEVIATION. CTLR WAS EXTREMELY BUSY WITH 3 - 4 OTHER ACFT IN THE AREA.
