To stay 'real', I wouldn't use 'dBi' gain figures for ERP calculations. As you can see, it can make quite a bit of difference. The problem with those isotropic figures is that they only hold true for 'ideal' or 'free space' calculations, not for 'real world' stuff. You would be closer to 'true' if you deducted 2.1 from that 'dBi' gain figure. Still not 'real world', but closer.
