Per ESA, JWST has a total of ~150m/s DV available. So all the statements do not match each other very well. However per NTRS there’ll be a 58-63m/s DV consumption during commissioning. So the 93m/s DV mentioned might be the DV available when the S/C becomes operational at SEL2. pic.twitter.com/GlIpuWb1Dp
