The group SMF and CBMF fall off more steeply at high masses and rise with a shallower low-mass slope than the theoretical halo mass function (HMF). The transition occurs at the group-integrated cold baryonic mass M_bary_^cold^~10^11^M_{sun}_. The SAM, however, has significantly fewer groups at the transition mass ~10^11^M_{sun}_ and a steeper low-mass slope than the data, suggesting that feedback is too weak in low-mass halos and conversely too strong near the transition mass. Using literature prescriptions to include hot halo gas and potential unobservable galaxy gas produces a group BMF with a slope similar to the HMF even below the transition mass. Its normalization is lower by a factor of ~2, in agreement with estimates of warm-hot gas making up the remaining difference. We compute baryonic collapse efficiency with the halo mass calculated two ways, via halo abundance matching (HAM) and via dynamics (extended all the way to three-galaxy groups using stacking). Using HAM, we find that baryonic collapse efficiencies reach a flat maximum for groups across the halo mass range of M_halo_~10^11.4-12^M_{sun}_, which we label "nascent groups". Using dynamics, however, we find greater scatter in baryonic collapse efficiencies, likely indicating variation in group hot-to-cold baryon ratios. Similarly, we see higher scatter in baryonic collapse efficiencies in the SAM when using its true groups and their group halo masses as opposed to friends-of-friends groups and HAM masses. 2017ApJ...849...20E https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/849/20 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006) J/ApJS/167/1 : Galaxy groups and clusters from SDSS (Berlind+, 2006) J/AJ/142/170 : ALFALFA survey: {alpha}.40 HI source catalog (Haynes+, 2011) J/MNRAS/436/34 : GALEX Arecibo SDSS survey.
