Tellor works by selecting the top five tipped requests for each Tellor block. As an example, assume ID's [1,2,3,4,5] are currently being mined. If ID's [6,7,8,9,10,11,12] have corresponding tips of [10,20,30,40,50,60,70], then once the first ID's are mined, the ID's with the highest tipes (ID's 8-12 in this case) will be chosen. ID 6 and 7 will not be mined and will have to wait for a block where they are the highest tipped (this is very similar to gas prices and transaction fees on Ethereum or Bitcoin). If you for instance are ID 6 and want to get your ID included in the next block, you will need to tip >20 (you have 10 and need over 30).
