I hear you…, you’re right that there was some frustration with folks believing they/others had been dis-/advantaged unduly. I think in most cases it’s their game time decisions that resulted in the outcomes. I personally like this objective because it is very challenging to get a hole-in-1 consistently, and it really feels like one where if you let it get away from you the game actively battles you. But I’m going to argue here it’s not unduly random.
First off…only a Wish will award tiger loops; BAZZAR awards do not ever award Tiger Loops. If you have lightening lamp, fireball hurry-ups running, or the princess’ ruby lit, then a wish will never award 3 Tiger Loops, but otherwise 3 Tiger Loops is a possibility, as is start lightening lamp, and collect bonus. [edit: I’m told that if Tiger Loops are flashing and none of the other conditions are met a wish option will be 3 Tiger Loops. Unverified, but if that’s true, it’s completely deterministic.]
The BAZAAR may award Light Locks, grant a Wish, 15 Lamp Spins (also good for a Wish), or Light Shooting Stars. Everything else is useless to you. You can choose to not shoot the BAZAAR scoop when no wishes are lit, lest you are subject to the “disadvantage” of Light Locks.
If you get Locks Lit you’re blocked from Tiger Loops, but you can go for MB and use it to spin the lamp to get wishes which you can trade in for Jewels or Tiger Loops.
Some Jewel granting modes can interfere with collecting Tiger loops as well, but you can choose your modes with flippers ALA LOTR before shooting the Genie. You can also collect Tiger Loops reliably while no mode is active.
So…I’m going to argue a lot of what might feel capricious, is really almost entirely within control of the player. The player controls Genie hits and mode selection, they can timeout counter-productive lightening lamps/fireball hurry-ups before collecting a Wish, and can use a multiball to their advantage by spinning the lamp to build Wishes. They can choose not shoot the scoop when only BAZZAR is lit, minimize Genie hits, pick modes that don’t lockout tiger loops.
BTW, it’s only my deep respect for the caliber of players coming to Pre-Pinburgh events that make me subject them to this evil objective 
I’ll take the action to ensure the hints sheet calls these strategies out a bit better. Maybe this could be ORed with a score objective that allows the game to be played in a more conventional way but I think that takes the fun out of it.
