Plunderer's Ring vs. Gambler's Ring

[trent8086]

For farming I was using x2 Plunderer's Ring because it says "A ring that increases the rate of item drops". However I noticed it has 2 less Luck than the Gambler's Ring and so I started using Gambler's x2 for item farming. But in the end I did not notice a significant difference (though I did seem to get more shards with the Gambler's Rings).
I tried to chart drops out into a spreadsheet but I then accidentally deleted a field and got bored of trying to do it again. So anyone else have data that bears it out?

I don't have data, but Ctrl+Z will recover a deleted field in most programs that I've used for making spreadsheets.

I'm sure it's too late for that now, but maybe in the future?

Plunderer's Ring gives you more item drops because it multiplies drop chances by 1.2 which doubled stacked is at least 1.4 increase.

Gambler's Ring is merely a luck increase which can affect everything in the game that is RNG based including drops of items, gold, shards, crit chance, and 777 slot machines.

Yea I know I can undo. But this was an accident where I deleted a field and then filled it in and deleted something else. I tried to successively undo it but then all the numbers started to get weird. I was using the Google Docs spreadsheet. I will probably do it again when I get bored of crafting stuff, but prolly on paper and then transfer to a spreadsheet. I think my swapping monitors and stuff may have caused it as well.
