We compile 45 XRISM/Resolve measurements in 19 nearby galaxy clusters and place them on a common, emission-weighted effective line-of-sight scale, $\\ell_{\\rm eff}$. We compare the line-of-sight velocity dispersion $\\sigma_v$, bulk velocity amplitude $|v_{\\rm bulk}|$, their ratio $R_v \\equiv |v_{\\rm bulk}|/\\sigma_v$, and non-thermal pressure proxies. Disturbed non-cool-core systems are not simply higher-dispersion counterparts of relaxed cool-core regions.
