The starting limit or limit when new is large enough to cover the differences in stock new cylinders. Mahle has three or four difference sizes that fit into the 84 mm size category.

The cylinders will be marked 0-3 and although they (Mahle) seem to match pistons and cylinders well they only make one set of rings.

When we're building a performance engine we make the cylinder undersized , make the piston the match and fit the rings the the undersized cylinder. It's a lot of work but race/ performance engines always are.
