Issue in distance threshold parameter

Issue description

I was optimizing the clustering threshold, but there was unexpected behavior,

• number of speaker clusters: 2, distance threshold: 0.95, keeping rest parameters default
• number of speaker clusters: 2, distance threshold: 0.1, keeping rest parameters default
• number of speaker clusters: 6, distance threshold: default(0.7), keeping rest parameters default

what can be the reason for the different decrease in the number of speaker clusters on increasing(0.95) & decreasing(0.1)?
