// @description    [@@BUILDNAME@@-@@BUILDDATE@@] Boost the detail level of portals shown on the map by one zoom level. Good for small screens. Likely to increase request failed errors on larger screens.

    // yes, it is possible to increase this beyond "+1" - however, that will end up producing a rediculous number
    // of requests to the Niantic servers, giving many request failed errors/tile timeouts
    // (every increase by one requests four times as many data tiles)
    var z = mapZoom + 1;

    // limiting the mazimum zoom level for data retrieval reduces the number of requests at high zoom levels
    // (as all portal data is retrieved at z=17, why retrieve multiple z=18 tiles when fewer z=17 would do?)
    // very effective along with the new cache code
    if (z > 17) z=17;

    // if the data zoom is above the map zoom we can step back if the detail level is the same
    // with the new cache code this works rather well
