DW1000 increasing anchors number increases frequency

Hi all, I’m performing two way ranging RTLS with DW1000 by using 1 tag that communicates with an arbitrary number of anchors. I noticed a strange fact, when I increase the number of anchors, the whole frequency of the system increases (actually I thought it would have been the converse). It is like anchors react faster when number of anchors in the system increases. Moreover, anchors are processed by tag in ascending ID order, and this fact I suppose will generate time latency. It is possible these events occur or there’s just an error in the code?
