Parker Barrows Five Finger Discount

[Virtus]

What does the reminder text on Five Finger Discount: "(the Upgrade must have the restriction of Parker Barrows and follow all other restrictions for attaching Upgrades at the start of the game)" mean?

Does it mean that if I wish to Five Finger Discount with Parker I have to already have one Upgrade slot already available- or can I essentially get a fourth Upgrade and then discard down to three Upgrades, thus triggering Parker's Limited Supplies ability?

And what about switching between his Limited Upgrades? Can I start off with one, then Five Finger Discount into the other one and discard the original (because you can only have one Limited Upgrade equipped at a time)? Or do I have to have no Limited Upgrades attached in order to Five Finger Discount into one?

It means exactly what it says. If you would be unable to attach said upgrade at the start of the game, with everything else in your crew being the same, then you can not use Five Finger Discount to attach the upgrade. Rare limits, already have an upgrade of the same name, limited restriction, upgrade count etc...
