@PaddyO go back a few posts and look at the pictures I posted. I did mine today one wheel at a time but if you're lifting the whole bike at once , you can still use 4 jack stands at the locations where mine are.
Put a piece of old leather belt on top of them to keep from scratching stuff and then just ease the jack down until she just settles on the stands but doesn't unload jack. She'll be stable as a rock, yank and crank on it all ya want, it ain't falling.
I had a self inflicted stuff up with putting mine on my table lift which resulted in the bike and me getting pitched arse over teacup onto the floor.
Trust me brudda, you do not want one of these things landing on you. It is both expensive and painful.
