Narrative:
Aircraft X (pit./.mem) displayed a meter time of +3 when I accepted the radar handoff; meaning that I had to incur a 3 minute airborne delay. The aircraft was assigned 310 KTS or greater by the previous controller in order to separate aircraft X from another aircraft longitudinally. After ensuring separation; I assigned the aircraft 250 KTS in order to meet the metering time and comply with mandated performance requirements. In less than 1 minute; the aircraft displayed 1 '0;' meaning that the metering time was complied with. A 60 KT speed reduction should not reduce the delay time in less than 1 minute; meaning either the metering list was reshuffled without notice; or the computer generated data is inaccurate.
