Referring to a thread wherein a question was asked about minimum rebar bend radii, an answer was give that referred to Table 7.2 of ACI 318. This table gives minimum bend inside diameters, not radii, as a function of bar diameter. All of the bar bending provisions of ACI 318 Section 7.2 are stated in terms of inside bend diameter. If the questioner followed the starred answer given his bends ended up unnecessarily loose. See thread167-143536: Minimum bending radius for rebar?.
