SURVEY:AUTHOR1:PUBLIC_COMMENT[string]
A repeatability study takes more than clicking on links and running make scripts or the resulting executables. See for example Casey Klein et al at POPL 2012 for a repeatability study that went into depth. When we ran this study, we spent almost two years with one PhD student per case study.
