Dose weight is an outcome of getting the grind size and dose volume (filter basket load), correct for any particular bean.
Weight will vary from different beans/ roasts, age etc.
Forget weight to start with.
Aim to keep the filter "fill" level consistent by over filling with grinds, settleing, scrape level, then tamp.
Do that consistently each grind, and adjust the grind size to give the 25-30 sec extraction.
Once you get consistent results, you can do a empty/ filled weight check on the basket to establish the dose weight for that particular bean batch.
Be prepared to waste a few shots to get this correct.
