This is the post Ti burn profile up to MC4 with PET timings (begins at Ti burn).

I thought we got a third plot where there was a deviation between predicted and required. Could easily be wrong though.
The image above makes it pretty clear that I am (wrong that is) 
There are multiple displays that get put on the TV. The one you're referring to (RPOP) doesn't have the required trajectory, but one of the others (the FDO display with the orbiter attitude window on it) does have required trajectory. My bad.

Anyone have any info on this 'BSA" issue they are talking about?

They are discussing problems with a box called the Bit Sync Assembly (BSA) which recovers data waveforms transmitted by RF from the Hubble telescope before passing the data stream on to the Orbiter systems.
They are having problems establishing a "lock" with the Hubble at present (they thought it might have been a range issue before when they tried).
Picture of the box attached.

Have looked around for FD2 highlights, but no joy. Can anyone point me in the right direction? Thanks. (This rendezvous is so exciting, I can hardly stay in my seat; your coverage and commentary is exqusite.)

"The Bit Sync Assembly (BSA), facilitates clean telemetry between HST and the Orbiter S-band communications system by processing the data stream through a digital bit synchronizer board"

"BSA is physically warm" sounds like an unsettling "datapoint" (BSA? DSA? wasn't sure)

I think I was the one who got it wrong but its so late here I turned into a pumpkin about an hour and a half ago so what the heck.
Crew is still having trouble with the BSA.

There's a BSA overview presentation on L2. I'll bump it.
