I'm listening right now to the recording I made on the MR27024 (with an outdoor eight-metre wire aligned W-E). The signal was best around 2240 with very close to 100% audio decoding for five or six minutes. But by 2252 it had deteriorated substantially with only about 15% audio decoding, and by 2250 there was no apparent signal at all.
You were listening off the reverse lobe of the beam. The stated power is likely the analog equivalent. The Vatican is probably using ~ 125 kW in the digital mode. Furthermore, the ionosphere has been very unstable (auroral effects at higher latitudes as well) over the past few days so your reception off the reverse lobe is proof of the Vatican's wise and robust configuration.
