Zen master black tape fix......

Cover the GPS speed readout with tape - unless you are in the immediate presence of any other sailboat on remotely the same tack which then MUST be beat to any imaginary point. It might be good to know how fast you were going when you "beat them" in case you ever meet them in reality and they ask questions.
Black electric tape works best for altering reality because it is cheap, easily removable and does not require going below to turn off the instrument. Heading and depth are still useful so careful cutting and placement of said tape may be necessary. An expensive "sailing" knife may be required for such accurate cutting.
On VHF NEVER acknowledge if speed is through the water or SOG.
Generally speaking SOG is becoming the "new normal"; as are mens's pants waists with pleats or X PANDO! Waistbands are held in relation to the size of the average mature American male.
Theoretically it is possible in any monohull sailing vessel to do 9 or 10 knots with a 32 inch waist at 62 years of age. It just takes blind faith, great imagination, obstinate certitude or strategic placement of black tape.

Re: What is good speed to make...

There is something called polars for boats. I am not sure they are made for anything but race boats. But they are a graph that shows wind speed and sailing angle vs boat speed. This helps racers measure their performance with sail handling, rig tuning and boat handling vs theoretical boat speeds. You will need a boat knotmeter to make sense of it though as the GPS will only tell you speed over ground.

In order to test your true performance you can try a couple of things. Study your tide charts and do some trial runs at slack tides. You can't predict exact slack but around that time you know the currents should be minimalized around this period.

If you want to learn to maximize your boat speed, take out a racer one day. First stock your boat with beer and rum then bring some good food onboard, mention the boats condition and invite the racer out for a day sail. Sailboat racers are unable to turn down free food or a stocked bar. You will very likely learn some sailtrim and boating angles to get the most out of your sailboat.

Re: What is good speed to make...

It is a funny thing about chasing down other boats, which I don't often get to do. Yet it seems that when it becomes obvious that you can overtake one of them, they tack off on some lazy course with no intention to appear willing to take on the competition. Especially larger boats that can tighten up and move out well above my speed potential. But it is fun anyway.
