Just a couple things.

Before worrying about starting parameters, the base fuel table has to be dialed in close to perfect. The start tables are just a multiplier of the base fuel table, so if the base fuel table isn't tuned properly, messing with the start tables is just going to throw things further out of whack. You'll need a laptop and lots of driving to get that base table dialed in first.

On the Pink wire, it needs cranking voltage as well as key on voltage. Holley says they don't like to see less than 10 volts while cranking for that pink wire, so you'll need a meter on it to test while cranking to see where you're at. I've seen them drop to 7-8 volts and not start, causing extended crank and hard start scenarios where they would sometimes catch and start just as you let off the key. But most of the time they would just crank for long periods and not start. You may find you'll have to move that wire around to a good spot that has strong voltage at crank, or run it through a relay.

Both of these things have to be checked and fixed before I'd worry about the startup tables.

Also the base fuel prime setting (key on) is 150% so it sounds like someone already turned that down for some reason (you found 110%)
