While we hear a lot about home AC L1 & L2 charging along with a flood of online videos focusing on the fastest DCFC experience that can be had for road trips there seems to be very little information on using lower rate DCFC. These slower chargers are often disparaged, however they can round out a charging plan and also sometimes prove to be good options for reducing costs and adding flexibility.
Here is the charging performance I have seen, so take it as you will and see if the time vs performance vs cost may help you given whatever chargers are nearby that you may have skipped in the past.
Vehicle: 2024 Silverado EV 4WT (205kwh/Max Battery)
Charge Power: up to 50kWh
Speed: 25% per hour
Charge Curve: Linear Performance
The truck takes the full 50kWh per hour all the way up to 100% then tapers off as it completes the charge in the last few minutes.
Charger Power: 125kW
Speed: ~60% per hour
Charge Curve: Linear Performance to 80% then tapers down to 50kWh at the completion of the charge.
Example: this is the charge curve for a 23%-96% charge at about 68F with no preconditioning and started at about 106kWh and increased steadily up to 122kWH at 80% then tapered off for the rest of the charge.

Charger Power: 150kW
Charge Curve: I have not tried a 150kW charger so I dont know if it just has an earlier taper point or but I believe it will more closely follow all the published charge curves. Post below if you have any specific observations at 150kW.
Charger Power: 178kW at Tesla V3 & V3.5 Superchargers
Charge Curve: Feels like it will follow published high power charge curves. I only used these in my first few days of ownership so did not observer closely. What I do recall is a quick ramp up to 178kW then tapers down over the charge. It may come down to that same 125kw @ 80% before the final taper but I cannot be sure.
