DOES THE HDK SUSPENSION K-MEMBER HANDLE BETTER THAN A T-BAR SUSPENSION?

This is irrelevant data since it isn't bolted to a car. You're also pulling on shock towers that have been known to have some failure problems. HDK doesn't use this design.
Excuse me?
The pictured test goal was comparing an unmodified unpictured RMS K frame to my modified RMS K frame pictured in #121. It's data, ignore it at your own risk.
You neglected to mention the shock towers you refer to are also the coil over towers.
Frankly, your comment here is at least, irrelevant.
I have yet to hear any verified reports of RMS shock/coil over tower failures. And sorry, the HDK does indeed use the RMS basic design, with minor changes, not all IMO exactly positive.
If you don't understand the previous meaning of "pinch" here used previously, you might want to remain on the sidelines a bit longer.
