Sempre coloco meus ambientes flutuantes no final do parágrafo onde foram referenciados pela primeira vez.
Mas tenho um problema quando o parágrafo é dividido em duas páginas (começando na parte inferior da primeira página e terminando no topo da segunda página). O float pode ser colocado facilmente no topo da primeira página, pois é referenciado diretamente na primeira frase do parágrafo que está na primeira página, mesmo que o float também esteja nesta página. Mas o Latex coloca o float na segunda página, resultando em uma primeira página meio vazia (por causa do float agora ausente) e uma segunda página meio vazia (porque o float agora é a única coisa nesta página).
Existe uma maneira mais fácil do que mover manualmente o ambiente float na fonte antes do parágrafo (com todos os problemas quando a condição acima mencionada não é mais válida, por exemplo, quando texto adicional é inserido)?
