Making arrows, and I'd presume bolts, was quite expensive, and so an archer might have a few dozen or so, potentially for an entire campaign season. While many replacements could be obtained on the battlefield, even during combat, you've still got a basic issue that a high rate of fire burst is going to be short lived thing in a battle and might only be possible a few times. That could be decisive if used enmass at a crucial point as the English managed a couple times, but it could also just be a wasted effort in a long engagement. How fast a crossbow user tires will not matter so much if the battle goes on for hours with varying intensity.
We do have some pointers on ammunition availability, price and production times.

100 bolts are worth ten and a half pennies, just a bit under a shilling. (
old english money conversion.) (I personally think it is quite interesting that he only worked 250 days a year.) Bolts are more expensive due to the dimensions, but are actually quicker to make than arrows due to their size (which makes forming and straightening much easier), needing no nock, and only having two vanes, usually made of leather.
Having carved and fletched quite a few arrows, myself, I do believe that 100 arrows per day would be quite an achievement, I'd assume that an average fletcher would manage something between 50 and 100 per day.

The Gascons under Edward I in 1283 brought with them 70,000 bolts in 29 barrels and 12 baskets...
Considering that the English are thought to have had an army consisting of around 5000 infantrymen and 1300 heavy cavalry in Anglesey, even if half their troops were crosbowmen, that's about 70 bolts per man. I'd assume a conservative number of 1000 men, meaning they had 170 bolts per man. (Probably having runners resupplying them during combat, I read something about that about archers, somewhere, but can't remember where.)
edit: I just stumbled over a quote that Genuese crossbowmen held 20 bolts in their quiver.
A minute's thought suggests that the very idea of this is stupid. A more detailed examination raises the possibility that it might be an answer to the question "how could the Germans win the war after the US gets involved?" - Captain Seafort, in a thread proposing a 1942 'D-Day' in Quiberon Bay
