Forcing amaryllis bulbs in water for repeat bloom: A Leafy update

My 'Double King' amaryllis bulb in a Nov. 2017 photo and a Nov. 2016 photo (right). The shorter 2017 leaves, I believe, resulted from days outside.
I have been growing the same 'Double King' amaryllis bulb in plain water since December 2014. It has become a pet houseplant, named Leafy, and it has flowered each spring (three seasons) since then with diligent weekly water changes.
This winter, I didn't have time to experiment with forcing hyacinths in water or forcing tulips in water, so I'm really counting on Leafy to bloom again this year.
As promised in a post months ago, I called up Hans Langeveld from Longfield Gardens in Lakewood for tips on improving Leafy's health, as the lone survivor of three amaryllis bulbs I got from his nursery in 2014.
The conversation took place way back in June, and I took notes on this expert grower's advice.
But I didn't do most of what he advised for various reasons. 'Splash' and 'Magnum' gone, but not forgotten.
For one thing, he suggested that in the fall I chop off the very leaves that give the bulb its name to put Leafy into dormancy. (Pipe up shock-horror music recalling how I previously killed the other two amaryllis bulbs trying to do just that.)
But the first thing he wanted me to do was to plant Leafy outside.
“You don't want to go back to soil?” he asked almost incredulously with his gentle lingering accent.
