However, injected external squeezing (IES) {\\it cannot} enable a practically interesting increase in the signal-to-noise ratio (SNR), and simultaneously, the increase of the SNR due to the use of intracavity squeezing (ICS) is even {\\it negligible}. Here, we {\\it counterintuitively} demonstrate that using IES and ICS together can lead to an {\\it exponential} improvement of the SNR for any measurement time, corresponding to a measurement error reduced typically by many orders of magnitude.
