Do we have an idea of how long will this 1M USD be used? One of the issues with bounties of large sizes is that expenditure was either too small or extremely large and required constant refills. A budgeting requirement is required for bounties so we don't have uncertainty regarding its refills and we can approve a more or less known amount that's to be spent and project expenses safely and without surprises down the road.

As a second point, we would like to know a way to describe success for this bounty and these mini-grants that Polkadot would be giving to multiple parties. One of our main concerns with hackathons and prizes is their impact. So far, a very minute portion of these submitted projects to hackathons have been continued as a real Polkadot project and even a smaller amount have been of sufficient quality to be considered for funding (We recently had a project submit to OpenGov a UI generated by AI from one of the first ranked websites). So what in your view is the best way to approach this assessment of success for these multiple potential grantees? Preferably speaking with numbers and actual projections. This is important so that in case of a potential refill 12 months down the line or earlier we can assess whether this bounty had success and impact or not.
In short, we certainly would like to avoid the hackathon chasers to deplete this bounty with mini-projects that won't entail anything significant.
