Narrative

I WAS WORKING THE LOW ALT (0-FL230) WINDSOR SECTOR AT ZOB. THIS SECTOR IS AN OUTBOUND SECTOR FOR DETROIT APCH CTL. THERE WAS EXCESSIVE TURB IN THE HIGH ALT SECTOR OVER MY AIRSPACE SO THERE WERE SEVERAL OVERFLT ACFT IN MY SECTOR THAT NORMALLY WOULD NOT BE THERE. ALSO; ADDITIONAL ACFT NOT ON PREFERRED ROUTING IMPACTED COMPLEXITY. TFC WAS BUILDING AND SECTOR BECAME EXTREMELY BUSY. DETROIT WAS SUPPOSED TO PROVIDE 15 MI IN TRAIL OVER 2 FIXES INTO MY SECTOR. THE AIRPLANES BEGAN TO ENTER AT 10 MI IN TRAIL; THEN QUICKLY BEGAN TO COMPRESS. I CALLED DTW TO ASK FOR MORE SPACING. AT THAT POINT MY SUPVR TRIED TO PUT A TRACKER IN TO HELP. DUE TO CONFUSION OVER VSCS PROC; I LOST COM WITH ACFT 3 OR 4 TIMES. MY D-SIDE WAS STRUGGLING TO PUT IN REVISED ROUTING FROM TMU AND COULD NOT PROVIDE ASSISTANCE. DETROIT HANDED ME A DC9 (ACFT Y) FOLLOWED BY THE A320 (ACFT X) WITH A 70-90 KT OVERTAKE WITH ONLY 5 MI SEPARATION. NEEDLESS TO SAY; 5 MI SEPARATION WAS LOST QUICKLY AT 13000 FT. LOA STATES THAT DTW SHALL PROVIDE 5 MI INCREASING BUT TODAY THEY WERE SUPPOSED TO PROVIDE 15 MI INCREASING. THE TRACKER NEVER MADE IT IN. I WAS DISTR BY ALL OF THE CONFUSION. I'M NOT SURE WHO ACCEPTED THE HDOFS. I ISSUED NO CTL INSTRUCTION TO EITHER ACFT. SEPARATION WAS LOST IMMEDIATELY UNTIL I CLBED THE LEAD ACFT.
