Simple H1 range projections with squeezing

I have been asked what would be the H1 range operating close to the best performance seen so far, with squeezing injected. Here I quantitatively improve my immediate answer ("not 120 Mpc"). 

I made a very simple projection by rescaling an approximate H1 shot noise model by 1, 2 or 3 dB of squeezing (I ignored radiation pressure here). To be clear: the squeezing projection doesn't rely on any loss model, I am only showing the improvement for these hypothetical levels of measured squeezing.

Data set: I used the Dec 9 "Holiday Party" data (200s starting at 2018-12-09T2:45UTC) assumed H1 was shot noise limited around 1 kHz and matched a gwinc model to shot noise. Jeff kindly provided the calibration to convert H1:CAL-DELTAL_EXTERNAL_DQ to strain (with some uncertainty ~10%). At that time SensMon was reporting 90 Mpc - gwinc on averaged data gives, as usual, 5% less range (~86 Mpc).

The plot shows a:
