Bug description

Some scores seen on leaderboard have an accuracy lower compared to stable by 0.01% (possibly due to wrong rounding??)

Yes, this is caused by rounding differences, because lazer rounds down to avoid showing (in other cases) 100% when scores are >99.995%.

osu/osu.Game/Utils/FormatUtils.cs

Lines 13 to 27 in 6a0ac4c

	/// <summary>
	/// Turns the provided accuracy into a percentage with 2 decimal places.
	/// </summary>
	/// <param name="accuracy">The accuracy to be formatted.</param>
	/// <returns>formatted accuracy in percentage</returns>
	public static LocalisableString FormatAccuracy(this double accuracy)
	{
	// for the sake of display purposes, we don't want to show a user a "rounded up" percentage to the next whole number.
	// ie. a score which gets 89.99999% shouldn't ever show as 90%.
	// the reasoning for this is that cutoffs for grade increases are at whole numbers and displaying the required
	// percentile with a non-matching grade is confusing.
	accuracy = Math.Floor(accuracy * 10000) / 10000;
	return accuracy.ToLocalisableString("0.00%");
	}

Not sure if this needs to be addressed - if anything it's wrong on osu!stable and osu!web instead of lazer.
