What’s your CYA? At this time of year 3-5ppm loss seems excessive.
Spots of algae even with chlorine 1-3

You need some cya (around 30ppm) or the sun will consume your fc quickly.
- also the drain /refill may not have eradicated your algae problem.
You can do an
Overnight Chlorine Loss Test at target fc levels
See —FC/CYA Levels
to confirm or deny whether algae is consuming your fc.
If you fail oclt its SLAM Process time.

Nominally that amount should raise your FC to almost 6. Other Texans can respond, but that usage this time of year seems pretty high (it varies due to climate/sun).
You likely still have algae that is quickly consuming it. Now with the refill, what are all your test results? If your CYA has lowered enough, time to buy a LOT of CL and follow the process for a SLAM. But post test results first before dumping and hoping.

To answer your question about normal fc losses - in an algae free pool average daily losses can be around 2-4ppm. As the weather cools & the uv exposure wanes this usually slows a bit. In the peak of summer some in southern states can notice up to 5ppm.

In central IL my peak loss was 3-5 depending on swimmer load. Last week my demand was .5-1 depending on swimmer load. We had one diehard taking the plunge in mid-60 water.

4-5ppm per day in heat of summer is not abnormal. A gallon a day sounds about right during the summer, but that should start decreasing now with less heat and less UV.
The key to avoiding algae is for your FC to never go below minimum.

With that said, you really need a SWCG (Salt Water Chlorine Generator) in N Texas. It's expensive upfront but 2-3x cheaper over the long run and with our long swim seasons, I wouldn't own a pool without one. You're going to find it harder and harder to find liquid chlorine this time of year, but the pool is still warm enough to need it.

Upper-90's over past weekend. My pool was still ~81º into last week.
