The upcoming wave of neutrinoless double beta decay experiments is geared towards probing the inverted mass ordering and transitioning into the normal ordering domains. We undertake a quantitative assessment of the projected experimental sensitivities, with a specific emphasis on the discovery potentials anticipated prior to the execution of experiments. We assess the sensitivity of the counting analysis using full Poisson statistics and compared with its continuous approximation. The inclusion of additional measurable signatures such as energy can enhance sensitivity, and this is accounted for through a maximum likelihood analysis. This study serves as an example to the generic problem of making sensitivity projections to proposed projects with predicted background prior to the experiments are performed.
