The estimation of the backgrounds for gluino signals in focus pointsupersymmetry is extended by including the backgrounds from the production offour third generation quarks in the analysis. We find that these backgroundsare negligible if one uses the strong selection criteria proposed in theliterature (including this analysis) for heavy gluino searches. Softerselection criteria often recommended for lighter gluino searches yieldbackgrounds which are small but numerically significant. We have also repeatedthe more conventional background calculations and compared our results with theother groups. We find that the size of the total residual background estimatedby different groups using different event generators and hard kinematical cutsagree approximately. In view of the theoretical uncertainties in the leadingorder signal and background cross sections mainly due to the choice of the QCDscale, the gluino mass reach at the LHC cannot be pinpointed. However,requiring a signal with $\rm\geq 3$ tagged b-jets (instead of the standardchoice of $\rm\geq 2$) it is shown that gluino masses close to 2 TeV can beprobed at the LHC for a range of reasonable choices of the QCD scale for anintegrated luminosity of 300 fb$^{-1}$.
