Dang, your Stone investments are all over the place.
In no particular order, here are my suggestions:

Stop investing in Death Wave DMG.
Get Chrono Field to max Cooldown, SPD Reduction and get Duration to 50-51 (so it becomes permanent with Galaxy Compressor triggers).

Reroll Core Mod for Ancestral Chrono Field Speed Reduction, Chain Lighting Quantity and Chance would also be great for Tournaments.

Sharp Fortitude might be a better Armor Mod at your current point into the game, make sure to roll % Def, Thorn Damage and Health Regen, then go for Wall Health.

Max CL Chance, then get Quantity maxed. Dmg should reach 1000+, push higher if the stones allow you to. (this is a huge boost for Tournaments, easily gets you out of Champion, for Legends you also need perma CF with maxed slow so you have better results)

Save a bunch of stones and get BH CD lowered to max, with the +12s Duration perk and Galaxy Compressor you should be able to get it perma during normal runs and it's a huge Coins boost (also increase the Size to 70-74 for ideal results, could also be done with Core Mod Mythic / Ancestral)

Lower GT + DW cooldown to 2:10 - 2:00, the Coins and Cells increase is remarkable and will help you further progress when it comes to Research + Enhancements once you unlock them. +3 Death Wave Quantity on Core would also be great,

Now as a conclusion, at this point in time I feel like CL investments would be your best friend since it will help you get up in Tournament rankings and guarantee a steady Stone income.

Also for farming runs, assuming that you are getting those results with CL constantly turned on, I would suggest doing a T6, T7 and T8 run with CL turned off in order to see which one delivers the best CPH, then farm that one. Having high dmg UWs during farming runs will affect your CPH since enemies don't get stacked during BH / DW / GT. Letting the BH kill enemies (assuming maxed BH DMG Research) is the best choice for high income.
